BlackBerry® Curve™

[renes92]

Hello, my Blackberry Curve 8310 switched itself to GSM about a week ago and I remember it being on the EDGE network. I am really dissapointed because I cannot send/receive MMS messages. Can someone please give me a solution so I can switch back to the EDGE network?

With the BlackBerry device powered ON, remove the battery a few seconds and then reinsert the battery to reboot.

Give it 5 minutes to reboot and settle down from all the initial data activity.

Does your EDGE signal return? 

If not, you could have a local tower issue, which do occur from time to time specific to ONE cell tower for your carrier. I know my best friend across town from me went a week with EDGE service at his hime only (travelling to another part of the city, he got EDGE) where he only had "edge" or "gprs". About 5-6 days later, he said EDGE returned to his device when at home.

I already tried those steps JSanders, and it seemed to return back to GSM. I think it is my Blackberry though because my Mom just got a Blackberry Curve as well and hers says edge. So i dont know why mine just switched itself to GSM, but I was wondering if there was anyway to just switch it from the options?

No you can't switch those optons.

Does it only get GSM wherever you go, all over town? You may need a SIM card swap from your carrier. 

Who is your carrier?

[renes92]

Yeah it does stay on GSM. And I have AT&T. I just dont understand how it was ALWAYS on EDGE and now all of a sudden it switches itself to GSM. Weirddd.

I'm telling you , try the reboot again, with the device powered ON.

I tried that Jsanders, I did it twice just now. And it still returned to GSM. Would I just have to completely remove the OS 4.5 update? And switch it back to the original factory one?

[JSanders Resident Expert]

Upgrading to OS 4.5 shouldn't make any difference in the EDGE or GSM signal. It might have been helpful to know that this signal difference all occurred only after you upgraded the device to 4.5.

But if you want to downgrade back to that and see... sure, try that.

I am having the EXACT same problem as renes92. I've taken the battery out with the phone ON like 10 times, the SIM card out like 5 times. It's so frustrating. Please help.
