Customer Ratings & Reviews

It will not work with all unlocked phones. Works on specific phone. Customer service not super helpful

This SIM card is versatile, easy to activate, and works with any unlocked phone. It offers affordable plans, no contract, and reliable network. It also has international features and hotspot capability. The online management tool is very helpful. This is a great option for prepaid wireless service.

Bought this sim and activated. But after that got many issues with international calls. Contacted H2o customerservice but no use. So shifted to another service provider in 2 days.

Horrible customer service, didn't work well either.

Not works well with certain phones and with att and t locked phones and unlocked phones

Only paid 1.00 and came home to hook it up and called and they told me it was outdated and they I would have to get a new one.

This Sim card did NOT work and would not work. No matter, what we did to make it work. Horrible product.

I found this item to be useless. Anyone with a plan did not want or need this item. I did not need it and could not find anyone who wanted it for free.

The most horrible product. Broke the minute I used it! And stuck inside my phone now I can't use it at all. Don't not waste your money!

wouldn't work if you buy online and come here for the sim

do not get h20 period.. if you do you will b wasting money ! and a phone

Put it in. And not 24bhoursv later, I received a msgood it didn't work anymore

Easy to use sim card for just grab and go for my mobile, i love to have AT&T network in my sim, so that i choose H2O wireless and it works great for me.

I've been using H20 for over 3 years now after moving from Simple Mobile. Very economical with quality service. I'm paying $27/month for unlimited call, text and internet. They also provide free $10 bonus unit every billing period that I use to call my family in Africa. Thanks H20

I have used H2o in Android and Blackberry AT&T phones for quite a few years and the deal keeps getting better. $27/mth with auto renew, talk, text, data and the added bonus that you won't get with anyone else: international talk direct dial (listed 50 countries for unlimited) and international txt. Best of all there are no surprises at the end of the month.

Excellent product that was easy to install on the phone

Perfect everything all was amazing thank you on this order. All was as expected. The other order wss the issue and lost the money.

I am not a person that writes many bad reviews but if I can save one person from choosing this company for their wireless service it’s worth it. To make a VERY VERY LONG story short, we switched to H2O for the AT&T backbone and to avoid fees. To start, their website is vague and tells you almost nothing about all the features you lose on your iPhone when you switch to them (no more FaceTime, audio/video files cannot be sent via iMessage, etc). They also don’t tell you that you need to configure your phone for cellular data after you are activated! WHAT????? We had no service save for WiFi. Then the real fun began when I decided after the FIRST DAY to just cut my loses and move directly to AT&T. After MANY trips into a local AT&T store to switch over from H2O the verdict was that H2O was holding our numbers for ransom. We have 3 phones. The first one ported over with no issues. The other two were placed on a hold by H2O. We were told we needed to be with H2O for at least a week by their (ONLY??) rep. He said “the system” wouldn’t release the numbers and there was nothing he could he could do. When I asked him why the first number ported fine he had no answer and kept saying it was “the system”. When I asked to speak to a supervisor he said he was the only one there. Is this a one-person company?? So the other two numbers were held hostage until the next week. How is that even legal?? I would STRONGLY RECOMMEND not EVER choosing this company for any reason.

H2O offers great prepaid plans..perfect for giving out to kids.

Excellent Sim Card and Great price i highly recommend this to anyone
