Customer Ratings & Reviews

I only used it as an adapter no Sim card was used.

I used to pay $85 a month for the exact same service. Now I pay $40. Money in my pocket.

This Product useful for people who don't like to make any commitment for long contracts(like me). and it works on most unlocked phone (I used it for 3 different phones it worked)

This is very good for a temporary use. Easy to sign in, easy to use. Good for calls, very bad for msg. Some times the msg arrive on next day.

I would use this again. It took me longer to set up than I was hoping, but I ultimately got it to work. Reloading the card was pretty straightforward.

Wife, Mother In-Law and myself have all switched from AT&T to H2O. No unlocking required since H2O uses AT&T towers. The data plans could be a bit better but overall we're all happy with H2O.

This SIM card is good value. You need to buy credit in order to activate it though which was frustrating at first, but it was easy enough to buy the credit elsewhere.

I had really good coverage with my H2O Wireless account. Id still be using it but I dropped the phone the Sim card was in in a sewer drain and I don't have the money to purchase a whole new phone and sim card

Had a cell phone that my contract expired on this worked perfectly for continued use and at a cheap rate

H20 has a nice paygo plan that costs $10 and is good for 90 days. Very useful for an occasional use phone.Att network, great coverage.

This service was a little confusing to set up but the customer service rep was very helpful. Since connecting, I've been very happy with the service and coverage and now I can just renew monthly online.

I bought this product for the third time, because I saved a lot of money when I started use this product

I did not realize this is not the size of the SIM card needed for the iPhone 5, but I trimmed it, and it works fine. You can find directions on the web for how to trim the card.

if you don't have too much phone calls and don't use data. h2o has the best $10 plan for up to three month. like it.

The H2O wireless sim card is okay. It's affordable, easy to install, and you can use it whenever.

Its a SIM card- easy to use and does what it should. Great service from H20 so far, too, and easy to check balance on the account.

Purchase this sim for my mom AT&T phone and she loves it. Good pricing, good rates, and easy to manage.

I wanted to ditch my land line, so I grabbed one of these and ported my home phone number to an old iPhone. Great way to trim the $$$ fat. Now my home phone is still active for $10 bucks for every 90 days, instead of $40 per month. Plus H20 has excellent service and great coverage.

Great domestic call quality. Tried to use this service for my international call needs and notice that the call quality was very poor.

Great Sim card. i get reception everywhere i go. $10 for a Sim card is a great price. I just love my new net work.
