I can send text messages, but I can't receive any, and there's a loop at the top of the screen that wasn't there before. How do I fix this?

Hi, issues like this are related to your Sim card (network),
not your Cell Phone . In most cases, regarding the text messages,
the problem is from the Service Operator. Have you tried the Sim card on another phone? If not,
remove the Sim card, insert it on another phone and try sending a message from another mobile to you number,
or you can do it in vise- versa by inserting another Sim card on your mobile.

If you can't receive text messages even when it's inserted on another handset,
then you will need to call the customer care of your Network Operator and tell
them your problem, they will help you fix it immediately.

You can check the message center number, but I don't think
it's very much important in your case, well, if you wanna try,
just check the text message settings and verify that the message
center number (which is currently in use) is the same number which
is on another phone with the same network (the other Sim should be
of the same network in your area). If it's different, make the changes
and save the settings. Also disable the "Receive Via" or similar settings..
(I can't recollect the exact settings as i don't have the same model with
me, please excuse me for this.).

If the same Sim card doesn't receive text messages using another handset,
don't bother to change the settings or to make any changes with it,
first call the customer care and verify from them, you may make mistakes instead of fixing it.


Hope that helps.
