Okay, this is frustrating.
Last night I text my friend saying "text me when you're nearly there", referring to my local. 45 mins later I got an angry phonecall asking where I was.. A few hours later in the evening I turned my phone off and on and recieved texts such as "waiting for a bus" and "nearly there, see you in a minute"
Today I text a few friends and not getting my usual reply decided to investigate. I got my sister to text me twice and used the service www.cbfsms.com/ to text myself and haven't recieved anything. I've turned my phone off and on numerous times and put my sim card in an old phone. When I put my sim in the old phone I got a couple of texts from giffgaff with internet settings but didn't recieve any of the texts I was expecting..
What figures? my phone's an xperia x10 mini pro and I can still make/recieve calls and use 3gs fine.
Thanks for any help.
