These guys are always so helpful, kind, and easy to work with. They make a trip to AT&T something that does not need to be dreaded, and I can actually look forward to, which is not always the case at other stores! read more

Raza and his coworker(Justin?) were a blessing. My phone died on a Saturday and could not get any assistance and after being passed along to many customer service reps, I went into this store and they fully restored my faith in customer service. From helping me set up my phone and cloud, and just being straight shooters. I can't recommend this store enough for quality assistance and help with AT&T and phone issue. i would have saved two days of stress if i just started at this store read more

Raza and Kevin were great! Really on the ball... what a pleasure. They really know their stuff. I will have a happy new year thanks to them. read more

I wish I could give these guys a 100 stars! After trying to dissect our family cell phone plan at home, it was obvious to me that we were overpaying and had an outdated plan--and that as a registered nurse/first responder/union member we were eligible for multiple discounts-- if only the plan was in my name (as opposed to my husband's)-- after a debate w/ my husband plus hitting a brick wall in terms of my online research-- my husband prevailed and we decided to go in person to discuss our options with a human--it was a toss up between the park slope and sunset park store in terms of distance/parking-- but we are so fortunate to have somehow wound up at this location (I'm sure other locations are lovely as well-- but no experience at those :-))-- we had a general idea of discounts we thought I'd be eligible for-- but these guys found an even better discount than I had ever imagined--!! The process of transferring the numbers -- 4 total --into my name and out of my husbands was laborious and time consuming-- for them -- but the guys in the store smiled and never complained, just said they were happy to help-- we even left and went to a lovely bar next door with board games and snacks for the kids-- and they came to find us whenever we were needed for verification-- I can't remember the last time I had such an amazing customer service experience-- with any business -- large or small-- my only regret is that I didn't halt my own online research sooner and just go in and talk to these guys-- if you have att cell service -- or if you don't and are considering-- go in and talk to these guys-- you won't regret it! read more

Raza is the best! Above and beyond customer service. highly recommend this location if you are upgrading your phone.

Thank you to Kevin who patiently helped me while I was freaking out over a lost phone and made it all better, quickly and efficiently!

This is the best att store. I just had an incredible experience with David L. David went above and beyond. I felt like I was so high maintenance and annoying. David was so patient and helped me with so many options. He answered so many questions and helped me file an insurance claim for my smashed phone. And I bought an apple watch! i keep thinking that I'm going to switch to another service because I get frustrated with ATT but David (and his colleague) were wonderful. They were also great with my son. THANK YOU read more

Raza helped me and my Dad upgrade our old iPhones to iPhone 14 Pro easily. I am 100% satisfied with how quickly the process took. Great customer service. I definitely recommend this AT&T store. read more

Great service, and really nice guys, but Asi put a $15 per month insurance add-on onto my account (called "Protect Advantage for 1") without asking me. I wouldn't have even noticed except for the fact that I just happened to talk to my neighbor who has gone to this store before, and they did the same thing to her. She ended up paying for over a year before she realized. I'm sure Asi gets a bonus every time he signs someone up for one of these plans, so hard to blame him especially given how tough times have been recently. Still, I wish he woulda just told me he needed money instead of sneaking this onto my bill. People are really hurting right now, and that $15 could have gone to someone who really needed it. Now it's sitting in AT&T's bank account, and I feel taken advantage of. read more

I went in to inquire about an upgrade for my my daughter's phone and was told that there was a promotion available, but I would have to trade-in her old phone and pay a $200 repair for the cracked screen. We purchased the phone, but upon further investigation found out that that promotion did not require a trade-in at all. I returned and got the $200 back as well as the phone, but the salesman was rude to me on top of trying to scam me out of $200 and a phone. Be very careful if you choose this ATT Store. read more

I didn't have to wait long . The staff was helpful and efficient and was able to upgrade my plan while lowering the price.

I bought phones and a new plan here 3 years ago and I'm still having issues resolving so many problems that arose from dealing with how the rep in the store set us up and honestly lied about what was available to us as a deal. They told us we could get 2:1 on iphones. They told us we could get a company discount when I gave them my employee info. They told us we would get a discount on having paperless billing. They told us we would get a discount on an insurance plan that a special was being run on at the time. They didn't set any of this up and some of these promotions and features weren't even available when I talked to AT&T directly to try to resolve the issue. AT&T is still, 3 years later, sending us refunds to make up for the $1000 extra we we charged. I would have gone back to the store to complain and have them fix things but we moved out of the area. Totally incorrect info and sold us on things that weren't true. read more

Best store. They have the biggest selection and most options than the other store around. They are super knowledgeable on the phones and plans. They were very helpful and got me all set up fast. Thanks ! read more

Visited at lunch time on a weekday- Asi helped me upgrade my iPhone 8 Plus to an iPhone 12 Pro Max easily. He explained the repairs that my old phone needed because it had physical damage (screen cracked) and the mother board stopped working so it was useless to me. He was able to send it for repairs so that it had trade in value that could go toward my purchase of the new iPhone upgrade which was on promotion. I don't know anything about phones tbh but he made me feel confident that making this upgrade is worth it and affordable! I usually hate visiting mobile phone stores because it is confusing and has long waits. This visit was maybe 30 mins and he was super friendly, not condescending or dull like usual associates can be. Coming from a retail background myself it is nice to see when someone genuinely enjoys their job and forms relationships with customers! It did not feel transactional even when I was very close to reading in my phone at the location further up the street, which I had actually visited earlier that day I don't get new phones often but I would love to work with ASI again if I did need to. read more

I can[t say enough about the service I received at this store, especially from (I may have his name wrong) Raza. He helped us make the transition to AT&T. He figured out how to make the offer financially attractive. He dealt with all my questions about the phone and the service. Watching him interact with other customers I was impressed how he made each person feel welcome and taken care of. Great store. Great service. Great people. read more

Amazing service. Asi and the team hooked me up with a full iCloud recovery as well as insight on how to get a huge discount on my iPhone 12 purchase. Easily the best in-store phone experience I've ever had. can't recommend enough. read more

Love this location. I always take my iPhone to an ATT store rather than Apple. Ozzie runs a great store. I have gotten four or five iPhones from this location. Ozzie also greets everyone and treats them well. He's got a high energy and knows what's what. Today I upgraded again and was helped by Michael. Perfect customer service without being corporate. This is my go-to ATT store. I feel confident that they will get whatever needs to get done, done. read more

Amazing customer service! Great deal ! Great people carefully helped with my needs Highly recommended Cellphone store read more

Asi from at&t was incredible and I highly recommend you go to him if you're in need of a new phone! He was so kind in helping me to figure out what phone was best for me, and he went above and beyond to ensure that I was getting the best deal. He then waited over an hour with me to transfer my data into the cloud so that my new function would function well. I cannot thank him enough for his help! read more

I decided to have my mobile activated here. The showroom was very clean and bright. Asi, the Sales Rep, was very friendly, helpful and professional. He handled the process very efficiently, and I was on my way with my newly activated mobile. Definitely pay this location a visit and ask for Asi. I believe you'll walk away a satisfied customer. read more

Asi has provided myself and my family with attentive and courteous service for over ten years. I can comfortably and easily that say he is a top notch service provider and local vendor. He forms relationships with his clientele, remembering your wants and needs, and that makes a big difference. Whenever I have walked into his store, Asi has always greeted me with a glowing smile and has always gone out of his way to find me the best deal possible. He has delivered savings and value time and time again. I trust his advice, and I am quite and rather difficult to convince of anyone's trustworthiness. He has earned my respect for his knowledge of phone devices, service plans and promotions. He really knows his business and it can be confusing, and you will really benefit from this, because he really tries to navigate the maze for you, with your needs and budget in mind. He's a local business that truly deserves your business. Super highly recommended. read more

I started going to Asi at Cel-Tel at 228 7th Ave, in Park Slope, Brooklyn about 6 or 7 years ago, and he has been amazing. I have 2 kids and a business, so many phones. Asi has given me the best service, the best deals and answers all my questions, and solves all my problems. I have never had better service anywhere else. Sincerely, Rick Schwab read more

THIS IS THE BEST ~ LOOK NO FURTHER! Asi and staff are amazing, friendly, courteous, and beyond knowledgeable. I have been to other AT&T stores but there is no comparison to these guys. They know their stuff and make your visit enjoyable. My family have been loyal customers of Asi for years. I highly recommend him for your AT&T needs! read more

Stay away unless you like being lied to! wow hung up the phone with ATT after having gotten all the info i needed to upgrade my phone. I then called 3 local stores to see who had it in stock... the first two did not have it in stock but confirmed the information i'd gotten from my direct ATT phonecall. Then I called this place... the guy at this store gave me a bull**t story that things have changed and that I must buy phone at full price with installments and tried to convince me I would not be able to utilize the default ATT discount with 2year uppgrade plan here or anywhere else anymore, even when I told him that both other stores and ATT directly had confirmed were an option and even said was the way to go if i had 199 as i'd save $300... sleezy liar warning read more

The store is the only one I or any of my family will ever go to for any phone/tech plan needs! We have been clients of Asi for well over ten years, and he always gives the best advice, has the best products and does everything he can to save us money while still providing us with unparalleled quality. Most importantly, though, Asi is trustworthy and generous, and we always know he's looking out for us and making sure we get every possible deal and advantage. Hard to put a price on that! read more

Went to this location because the one up the street on Union was closed.. I was interested in getting a new iPhone and the guy working here spoke very quickly and had a phone out before I could even have a thought to myself. He then questioned why me and my husband weren't on a plan together, that it would be cheaper. I don't trust salesmen and told him I would look into it and decide later. He did the math for me and kept telling me "it's not that complicated" in a condescending tone. I told him I still wanted to think on it. He angrily says, "So I missed a sale by just trying to help you." Terrible customer service! read more

Asi is the man. Whenever I have a phone problem he handles it within minutes. I've been dealing with Asi for 7 years now. Never a problem. read more

Asi's the best! He was extremely knowledgeable and helpful...Would highly recommend them to anyone!

Great customer service!! I am not from the neighborhood but had an emergency with my phone so I stopped in the store. They are really knowledgeable and were extremely helpful with everything I needed. read more

**NO STARS** The worker is very nasty and very condescending. I made a purchase and had to return it because it was defective. He blamed me after having it for 3 1/2 days when at&t and Samsung said it was defective. Gave me a refund after fighting with me to return it and at&t said he had to return it then I get charged for someone else's purchase almost 2 hours after I left the store so now I'm trying to get my money back again. I am reaching out to the regional manager for at&t in brooklyn to deal with this read more

BEWARE! Stay away from Cel-Tel at 228 7th Avenue, Park Slope. Asi, the sales rep, is a shyster. If you read this great review about Asi, he is a great salesman as long as you keep your phone. But, if you decide to return your phone within the 14 day period allowed by AT&T, Asi will be resistant, difficult, rude and downright unscrupulous. We returned phones and were OVERCHARGED an arbitrary restocking fee which exceeded what was allowed by AT&T. We contacted AT&T and found that after we left the store, he tried to charge us an early termination fee of $325.00 per phone. AT&T reversed all the charges and filed a complaint on him. Do yourself a favor and use the other AT&T store a block away. read more

Went here to upgrade my phone. I had no idea they were going to completely change my plan as well until my bill was $30 higher at the end of the month. Very sleazy. read more

Misleading, disrespectful smooth-talkers. I was talked into switching plans under the premise that my bill would drop from $204 per month to about $140 per month. I was repeatedly assured of this. When my ensuing bill wound up being $208 after I had sacrificed my unlimited data, I went back and complained. I was met with empty promises to get me discounts to make up for the "misunderstanding", only to be repeatedly ignored when I called to follow up. After three weeks of being avoided I went straight to AT&T and got them to reduce my bill by threatening to switch carriers. read more

Thank you to Asi for excellent service. Knowledgeable Efficient Nice He helped me buy a new phone and to update a plan, and gave advice on how to deal with calls and data while abroad. read more

Over the past few years I've bought 6 full priced phones here and believed they did have the customer in mind. Recently they recommended I buy a refurbished phone when adding a line for my son. When it stopped working they said it was dropped and of course a refurbished phone is more likely to break which they didn't tell me when trying to sell me on it. They refused to do anything for us and didn't even offer to repair for a fee, just said "can't do anything for you." Being a loyal customer means nothing to them I guess. read more

Excellent customer service!! Asi is the best & everyone there is super helpful as well!Thank you!

Very helpful guy, and apologetic for the totally crappy ATT store just a block away.

Wonderful and so helpful! I needed a new iPhone after my toddler dropped mine in the toilet! The guy who worked there was great helped me right away! Deffinatly coming back when its time for a new phone again! read more

Whenever I need to have my mobile upgraded or fixed, I always go to Cel Tel. Asi is extremely knowledgable. He always manages to solve problems (no matter how difficult they are) in a professional manner. I highly recommend Cel Tel for all of your mobile needs. read more

I generally don't like to put out nasty reviews, because it seems like bad karma, but I have had a series of really bad experiences here. I got a phone here, which stopped working spontaneously within a matter of weeks. They were nice about it and exchanged it for another of the same model, which I'll give them credit for, but then the second phone stopped working because it would no longer charge. So I went back again, exchanged it for a third phone, this time of a different model. Now, my third phone from them will no longer charge, so I have to get a new one. Again. Granted, they were nice about it every time I went back, and even acknowledged that they knew I had been back to exchange broken phones a bunch of times, but there's no way that I am going to go back there only to get a phone that's going to break in two months. read more
