This is a full review of h2o prepaid wireless phone plan. I will be going over things such as speed test, overall day to day usage, signal strength, APN network setup, and price point. H2O uses AT&T satellite network where as Mint mobile uses T-Mobile. Both are equally as good and fast, depending on where you are using the phone. Some places AT&T signal is better where other places T-Mobile is better. I just want to show you that h20 wireless is just as fast as any other service out there and with NO contract, you can cancel at ANY time. I am using a gsm network Umidigi smartphone, unlocked, to do this review.
