I bought a Samsung 4, 3 or 4 months ago and upgraded to a plan with 50GB of data. My data usage is zero so I should not be blocked. I checked my IMEI with the tool and everything is compatable. My Mobile data is turned on. I'm not in airplane mode. I've removed and reinstalled the battery twice. When I bought the phone I told the guy I probably would never use data. But now I want to use it.
When I turn on my phone I get a message that says [i]I have undelivered messages that will be sent when a service is available. I think these are 2 photos that I tried to send via text message last week.
When I start Internet explorer I get a message saying No mobile network available. I can use the phone to make calls.
How do I get my data to work?
