My tablet (Android 4.4.2) has 3G SIM card capability, and I can connect to the Internet (Data service) no problem at all. I can also dial a number and use device like a telephone.
However, using the Google Message app I cannot send a TXT ... the onscreen message says something like "cannot send at the moment but will keep trying". I also tried sending myself a TXT (from phone to tablet) but nothing came through. The app is linked to the SIM service correctly.
I am assuming that like a phone, i do not have to be connected to the Data Service to send TXTs ... the telephone call was made with just the SIM card activated, not on data.
Anyone got assistance please?
