Customer Ratings & Reviews

Easy set up. You will save a ton compared to all the major well known carriers. Great service! Best bang for your buck!

Was looking for a prepaid sim card that fits my International phone and this fits my needs. Good coverage, apt plans, good customer service and simple account management online.

Very easy to port existing number to H2O. Can be used on any unlocked phone. Great plans available on H2O.

Convenient and great as a prepaid card. Would recommend.

its great and I am happy with the purchase the plans are wonderful on the h2o website I have an iphone 5c and its works perfectly I took my sim to a best buy mobile store and they helped me put it in my phone and it worked so happy with the purchase I made

The Toshiba laptop that I got had the most reasonable price ever. I don’t think I dreamed of lower price for a great product than I have now. Also, I purchased an H2O SIM card, I am so happy with what I always get when I shop at BestBuy.

I purchased an H20 Wireless card, the card did not come with a pin? When I went to set my phone up with H20 Wireless they had to do a work around because my phone card did not come with a pin.

A prepaid wireless SIM card that will work with iPhone and saves you some money. Need I say more?

My wife's family lives in Indonesia, and when they visit we've found it very helpful for them to have a local SIM/number to use while they're at, say, the airport. We didn't have any trouble setting this up or adding funds. Looking forward to using it again next time they visit.

I bought this sim just to activate a Lumia phone just to get a phone number and then set up and use the wi-fi MagicJack app. Had to trim the sim and now having trouble unlocking Windows phone. I think a tracphone sim would have been easier.

if you are a young kid moving out on his own that needs your own phone line for school, this is it. you pay as you go. the new $30/month is perfect and gives you unlimited texting and calling. picture messages are dumb anyways, you can get that if you wanna pay another $10/month. but all you need is unlimited texting. The network is AT&T so you have the best coverage without their exorbitant prices on a plan with them. Go for it!

I really like H2O service because it's easy to sign up for, cheap plans and has good coverage.

I've been using H2O for a while and they have great affordable Pay As You Go and monthly plans. The SIMs are easy and quick to activate online with an ActFast code too. These are great to use on unlocked phones!

The H2O card popped right into my phone and was simple to activate and to sign up for a "plan" -- $10 that's good for 90 days, perfect for me as this is a "back-up" phone to my main cellular one. I'd used H2O overseas, so felt I could trust them here, too. But their international cell calling rates for certain numbers/places are crazy high, so it won't get used for that, for sure!!

I think this is a great wireless provided. It uses the at&t towers so coverage is pretty good, price is great!

If you want to save money by not paying too much for cell phone bills, this is a great option. I switched from atnt and I dont have to worry about my bill bring high.

The service is good. However, around my house, the signal isnot really strong. When i Made phone calls, i had to try couple of times. Other than that, it's fine

Price for a SIM card is pretty steep, but H20 service is reliable and easy to set up with an unlocked phone. Trying to figure out APN settings can be a chore sometimes though.

Was looking for something to work with AT&T iPhone 4s for less money. This works! I definitely recommend it.

Very easy to use the SIM card. It activated without any problems. Also it is Cheap and efficient.
