I have an Iphone 4, can't send any texts (I get an error as well) and I can't make or receive calls. I can RECEIVE texts though, which is odd. I've tried resetting my network, turning off phone. No dice. Nothing is working and I don't own a landline. Friend leaving for China was supposed to visit me tonight and I'm getting his texts but can't respond. Apparently the Ctrain is ALSO down, so I can't text and he's stranded. Lovely.
Not just smart phones are having troubles, but also other feature phones are too. And this is a two weeks after you posted this article. Get your act together and tell us what's up because I am also getting messages saying I have attempted to access the internet using an application when I clearly have not.
I'm having this problem with my LG C800G phone. I can't find anywhere in the settings that gives a message centre phone number, although under call settings there's a voicemail setting that uses the number +15149921123 (not +15149931123!). I can't change that however.
Fido's technical support people could not deal with it (or wouldn't) and gave me an LG number to call. LG couldn't solve it either. I can't find a reference to this wrong number anywhere on my FIDO SIM card using yet another phone, and I can't change it on my LG phone. I had the same problem with my Nokia E73 phone earlier this week when I put my Fido SIM card into it to replace a French SIM card. I found there were two message centre numbers, one French and one Canadian (Fido's). I deleted the French number and bingo, I could send text messages. However, LG's software doesn't mention a message centre number, only a voicemail number. And Fido says they're the same number. But the LG software won't let me change that number, which I think is the root of the problem, so I'm stuck with the inability to send text messages and no one who will assume responsibility.
