I did, but still not working. when i was trying to access browser i have got a message (you need to set mobile date on" and the data was on.
If the above guides don't work, you might want to try cycling the phone. Take the battery out for a bit, and then turn back on. Or, simply turn it off for at least a minute, and then turn it back on. I also take the SIM card out when I do this, and a lot of problems are often solved. If you still can't get it to work, rest assured and the PM mods will absolutely be ready to assist you!
you will need to have data working (even on non data plans) to be able to send mms messages.
as mentione what phone are you using, some phones like LG require a factory reset. did your plan activate correctly? ie does data addon show up in your self serve?
Can somebody ping the mods on this thread? I'm not sure how, but this issue seemingly needs moderator attention. 🙂
