Customer Ratings & Reviews

Very good sim card for that price. I will recommen

I first purchased an H2O SIM card for myself a few months ago. It gave me what I wanted for a very reasonable price. When my son wanted to get service for his iPhone I told him about H2O. He tried and and has already renewed his monthly service. You don't need to pay the big companies for cell and internet access.

I love my Samsung galaxy s21. the people were really helpful, especially Barney, in helping me find what I wanted. Overall just a great experience and I highly recommend going there for your electronic needs.

Best Sim for international usage from USA. Quick and prompt service delivery by Bestbuy.

Good and flexible products that have different offers one can choose from

H2O wireless service has good network connection in my area. It is very easy and fast to port in the number. Customer service provides excellent service.

This SIM card works as you would expect. The best part is that H2O has some very affordable phone plans. My service has been reliable for the most part.

The product worked well....No issues so far.......

Did not use it because I changed network hopefully it work find

Great and recently system is moving towards eSIM and until then it is a wonderful.

I have an unlocked gs8+ and am using this in it. I get better reception with this then I did with Sprint prior. And am currently paying 27 a month for 3gb of data. That includes the discount for autopay.

This plan has worked fine for us, my sons first phone and plan, seems to work just great, and easy to install and set up, friendly customer service support as of now, we have not Ra into any problems, so I can not say...

I host exchange students for 10 months of every year. We always buy this SIM card so the student can have a local phone number to use while here. There's a great monthly plan for $40. When they return home, they simply remove this SIM card and put their old one back in.

Honestly just got it to port the number out. I’m sure their service is fine though.

Got this chip only to setup an unlock iPhone for my mother before she traveled overseas. The setup was straight forward and it took only about 10 minutes.

I've always liked H2O as my service provider because it works everywhere I go.

Would be 5 stars but customer service takes forever to answer. I am not sure if it will automatically continue service or if it is default on by payment. Hopefully, the latter. Will update if it's the former.

In a Very nice packing easy to use and good quality product.

Loved the product. Instant purchase so, no waiting for the sim kit in emergency cases.

If you are in USA and wants to use cheapest plan with international unlimited plans and unlimited internet, this is the best. H2O uses ATT network.
