I have a Huawei Glory 868c and it was working fine yesterday but for some reason today it will not send a text. All I get is a red triangle and a "msg not sent" any ideas?
Call your carrier - they could be having problems. If you can make a phone call you should be able to send a text - they're the same thing to the network (up to the point of establishing a 2-way permanent-until-you-disconnect link for the call).
