I've been totally impressed with the wireless coverage with this service. I've traveled all around the Lansing area, over to Grand Ledge, south into Holt and Mason, even down into Charlotte (you'll lose it west of Ainger Rd though) and Eaton Rapids and have had great coverage with the service! I've had to talk to customer service a few times, and the wait times were pretty long, but they were able to assist me both times. I haven't gotten the wireless data to work with the iPhone 4 yet, although I've read that others have. I'm using iOS 4.2.1, again on a LOCKED device, and I couldn't be happer with this service, especially for $40/month for unlimited calling and texting! I purchased a locked iPhone 4 from a guy off Craigslist. I then purchased this wireless service, trimmed the included SIM to a Micro-SIM form factor, and inserted it into the iPhone 4. I connected the iPhone 4 to iTunes and it activated instantly, no problems!

Very happy with the service that H2O Wireless provides. They're an MVNO for AT&T, which basically means they're a sub-contractor that buys millions of minutes in bulk, and sells them to us, the consumer, at a discount. They use AT&T towers, so wherever AT&T works, H2O works as well. Your phone doesn't need to be jailbroken or unlocked, or anything like that. I just popped in the sim and my standard AT&T iPhone worked just fine. So, you might ask why wouldn't you just use AT&T? Because H2O is AT LEAST half price compared with AT&T! In some cases, AT&T is 3 times as much! I get the same quality of AT&T's service, without paying for the big name of the company! I recommend H2O to all of my friends!

Good price for the product. Easy to use, I activated my unlocked iPhone with this SIM card without any hassle.

Overall I can't complain ! I mean the service is good and I'm satisfied. My husband, myself , and our kid uses the service. Compared to AT & T and Verizon (The best service ever/ I can't afford there price for phones and service) I certainly will choose H2O Wireless because it's affordable and there's the added ease of being able to add minutes monthly without dealing with all the extra fees as I would should I have chosen to stay with Verizon or go with AT & T.

I switched the whole family to H2O Wireless, bought more than 5 of them, the Sim card are easy to use, easy to install, great prices, great plans...monthly or pay as you go! The greatest thing is the best value that you can use the SIM on any unlock GSM phone or event the AT&T phone not unlocked!!! Work great on my old AT&T iphone 4S...too
