Customer Ratings & Reviews

The SIM card works just as it should. The only issue I had was with H20 Wireless itself. I tried to transfer my cell phone number from a different carrier. Long story short I ended up having to buy a new SIM card due to TERRIBLE HORRIBLE customer service from H20 wireless. Unfortunately AT&T and Verizon are the only decent carriers in my area and H20 wireless is the cheapest out of the two low cost providers on the ATT network. So I'm stuck with them.

Great value and efficient service .. very economic

It has best network and the 3 in one sim makes it easy to get set up in each and every device .

H2O plans are worth it. You get what you pay for. Would buy again next time I need a SIM card.

Went to the store to try and figure out if there's any difference between the yellow SIM and the black SIM. There's about as much information in store as online - in other words, I still don't know if there's a difference other than packaging. Decided to go with the yellow packaging since those were the plans I was planning to sign up with, but I wish H2O would clarify.

Affordable price. Decent service. Works well as expected.

Sim is too good Easy to use Definitely suggest everyone to buy

H2O Wireless helped me in the past as a cellular phone service. I had to go back to them because my current service was going to be terminated. I purchased this Sim Card and ported my number to H2O Wireless in minutes without any delay in service. Worked perfectly.

It's very good and unlimited data with good coverage

The sim card has excellent signal! It comes in 3 sizes!

This kit was one of the better ones if you are looking at overall value vs. what the traditional larger mobile companies are offering. If you need a second line that is cheap this kit is the way to go.

There were some initial problems with getting this card to work with an older phone for all of voice, text, and data. But once the card was set, it works like a charm. H2O can be a good choice of provider for those who don't have strong T-Mobile signal.

Nice sim card and easy to be activated. good price too,

I like the services and the fact that one can make a direct call internationally and this makes it easy to talk to mom who does not have WhatsApp.

Great product. Had I done a little more research before purchasing, I would have known a plan purchase was required for activation. But overall, product is good buy.

H2O - 3-in-1 UniversEnjoy national GSM coverage through H2O Wireless with this H2O Wireless 3-in-1 SIM card, which can be used as a micro, nano or standard SIM card to give you plenty of options. Surf the Web and more quickly with 4G LTE speed (data not included).al SIM Card veri good

I got this h2o wireless sim card so I could experiment with a older iphone on wifi. It was great to be able to go pick it up at a Best Buy. You need a sim card even unactivated to start using a iphone. Plus I plan to activate it later on a phone, we love their pay as you go plan.

It is one of the best SIM card in market. BustBUY provide curbside pickup option for this and it is best for me. This is zero balance card, you need to recharge from h2o website as per your requirement.

This is the cheapest service with no monthly commitment. For people who just need a backup phone when they go for walks and stuff, this is great. I get this everytime for my in laws who visit us from outside the country. This service piggy backs on the AT&T networks and has great coverage.

This prepaid sim is great value for those that dont talk much or are on wifi most of their day. The monthly rates are decently priced. The cost of the sim is more than what i would have liked to pay for it but it all works out in the end.
