    H2O 3-in-1 SIM Card

    • This is the cheapest service with longest expiration you can get for your money
    • They do NOT support MMS (Multimedia Messaging Service) on the iPhone
    • Best Service and Plans.
    • Cheap reliable service on a sim that costs a penny with no shipping
    • So why overpay for brand name service you don't even need when this service is available?
    • The service is provided through AT&T and works well in my area (greater Boston).
    • lousy service!
    • Easy activation, very good service and coverage.
    • Great price for the H2o SIM card and H2o is a great cell phone service with some very low cost options for people like me who do not use a cell phone much.
    • Thanks to this service I can still have cheap phone service for my parents who barely use any minutes and use the VOIP line waaay more.
    • The best service, I Like it
    • H2O has the worst product service
    • H2O. Service works like it is suppose to
    • Poor customer service; difficult to get a live body on the phone
    • Absolute garbage product with no helpful customer service, poor instructions, and really caused a ton of problems for me.
    • I did not test the actual service, but as a SIM to confirm that your device is in fact unlocked, can't complain.
    • Affordable service with H20.
    • great customer service
    • I came from PlatinumTel, which was a great service but they shut down recently.
    • The service is excellent
    • Poor customer service
    • Not compatible with most, and WORST non-english speaking customer service ever!!!!
    • H2O wireless is an inexpensive cellular wireless service that works on AT&T network
    • Otherwise, H2O proved to have very good coverage and service, and flexible prices.
    • Right price, fast service!
    • about 4 or 5 years ago, maybe they've gotten better, but this is a different service, it just uses AT&T's towers to provide it, and other reviewers claim the service is fantastic, one mentioning better than AT&T

    • Cheap reliable service on a sim that costs a penny with no shipping
