Customer Ratings & Reviews

The kit is wonderful and self explanatory. No installation issues at all. Coverage is too good.

Perfect service if you don't want to commit to a contract. This is not for heavy users, more for emergency use and the occasional call or text. Great customer service. I called them several times and they were very helpful.

Great service ! great rate , must have a unlock phone , that works for AT&T , T-mobile ! they have a deal 20.00 a mouth w/ 2 g of fast internet plus talk and test .. its a great deal for sure , 3G and 4 G ..

their international calling is dumb, normally i would call a number with the proper adding of the extra numbers in front of the main number...it would connect right away, but this dumb company , you call an international number, the robot answers tells you how many hours and minutes you have left then asks you to type the number, ...

For a dollar it can get you connected to the AT&T network for a low enough price and that is good.

I got the H20 wireless card for my cousin who was visiting from another country and it worked perfectly right out the box,, setup just took a few minutes and she was talking, texting and surfing the net in no time

I live in Europe and travel home to the states several times a year. I buy 4-6 of these cards that I can initiate while in Europe and when I land I have phone service at a fraction of the international rates from my home provider.

I live outside of the United States, H2O Wireless Now was one of the first companies to offer sim cards that can be put into unlocked phones. I have been using them for nearly 10 years now and love the service they provide. My parents live in the US and also use H2O.

The sim card is 3-in-1 can fit different sim card slot. The active code is inside the package and easy to use for card activation by online, live chat, or phone call.

I was looking for a service provider who provides unlimited plans with international calling feature and decent data plan at an economical price and H2O fits the bill. Network coverage is pretty good too.

Works as expected. Please make sure the store clerk activates it properly otherwise it will not be recognized by the H2O website.

Perfect way to get your phone on H2O wireless. H2O offers low cost alternatives to traditional plans. I used it for my grandma who makes very few calls.

I absolutely love H20 $30 ($27 if you setup auto-pay) Unlimited Talk & Text plan which also gives $10 International Call Credit and 500 MB data. You really don't need that much data if you mostly use Wifi at home or office. Highly recommended. Works everywhere in US.

This is the first time I use for myself , try to avoid the contract, i found it very good to use , the signal have full bar but some time it drop my conversatiion. The signal for internet good in service.

This is MVNO which uses AT&T as the network, however few points to note is AT&T blocks few feature like MMS, hotspot. Its good if you just need unlimited phone calls and data

Very easy to use service active in a mints The value is very good

Best career just for voice and message. It is easy not to wait to get SIM card from career

Works fine good service. Dont know what else u want me to say.

Bought this SIM card for an unlocked Samsung Galaxy s6 and it takes a little to get it up working but for the price and the benefits that the plans offer it worth the buy and the set up time.

This is the 6th sim card from h2o i bought great card, great phone service i now have me and all my family on h2o with sim cards, i recommend these if your not sure which size sim your phone uses cause its all 3 in one.
