Customer Ratings & Reviews

I prefer using no contract plans, but I don't usually like the selection of phones. I started using the BYOP plan with another service, and it was such a disaster, I ended up switching to h2o. I have had absolutely no trouble with it so far.

Paid only $1 for SIM card at Best Buy. Active with h2o any plan and get 1 month free. Works same as AT&T on my new unlocked iPhone Xr. Ps. No contract.

It's just a SIM card, but provides access the the H2O GSM Wireless system (Which runs on AT&T's network). Been a customer for years, best pre-paid wireless deal around if you own your phone.

No problem to set up on unlocked phone.Solid plans to use.

Had this company for several years. Can't really complain. Good for prepaid service Just purchased new phone so needed another sim card.

It's just a SIM card. It works. There are better deals out there for service, though (especially four TMobile MVNOs).

I ordered the sim card one evening and picked it up the next day. I was very happy that I was able to get it so quickly. The salesperson was very nice and helpfull. Very happy with my purchase. Thanks Best Buy!

Better coverage and prepaid plans. Customer care is ok.

My friend that I bought the chip for couldn't get access to any network with his phone brought from Ghana but now is able to get access to the AT&T network in this area

Bought the sim for my wife. The only reason to go with H2O network is the free international calling feature. Network quality is okay. Got the sim quickly from best buy using the store pickup option.

Are tired of contracts and high monthly phone service. Get H2O, it runs on the ATT LTE network and data speeds are good.

Perfect for what I needed it for. Great little starter kit that comes with all the instructions.

It is exactly what it says it is; a SIM card for H2O wireless service. It is cheaper to purchase it from BestBuy then it is to order from H2O wireless.

It’s not bad ! But having some signal issue other than everything is fine

Excellent for people who are visiting or students. You can chose a pre-paid plan for as low as $10 with 200 mins/text and a validity of 90 days. Very good for someone like me who barely uses talk time/messaging.

It does exactly what it needs to do. For some strange reason, I initially had quite a bit of trouble fitting it into my cell phone. But now that it is within my phone, I never really have any issues.

I guess this piece of plastic does what it supposed to do but what I’m really bent out of shape about is buying an item for a dollar and being charged $.51 for an E911 tax. This is a piece of plastic! It’s not a phone or a communications device. The clerk just shrugged and said I don’t know, do you want to return it?This is the last time I buy anything at Best Buy in Virginia.

I've heard that h20 uses at&t carrier and so I took this sim. It asks for a number to enter for the successful sim activation. But that doesn't work. I have to call the customer care to get that sim activation. Signal is not that good. I gave 2 stars because of its free international calls offer.

I like H2Owireless. Their plan are affordable and they have good customer service. I've been with them for 7 years now and very happy

H2O provides some cheaper monthly and quarterly plans. Good for prepaid users who just need a phone number.
