Attention no service and mobile network not available

About 2 hours ago, my phone was blinking and saying attention no service (there were no bars at the time). Then when all the bars were full again, it is still blinking and saying attention no service. I can't make/receive calls or texts. I have turned the phone off, took out sim card/put back in and restarted it. I was still getting the same problem. It will switch between no bars to full bars but blinks and says attention no service the whole time. When it actually does stop blinking and no  longer says attention no service and the bars are full, when I try to make a phone call it says mobile network not available. It just keeps going back and forth with all these steps. What is wrong with my phone and how can I fix it? Or is it an issue with AT&T? I have to have a working cell phone before work tomorrow (well, actually later this morning now). Help! My phone is a ZTE Maven.

Greetings @tjtimes3,


I am so sorry you suddenly have no service on your phone! I would love to help you out.


Since this issue began, have you tried restarting your phone? Sometimes a simple step can fix this type of problem. If you have already tried this with no results, I recommend cleaning your SIM card.


Our Device Support page can walk you through with finding and removing the SIM card. Once you reach the page, please select your make/model – Tutorials – About your Device – Insert SIM card. After you remove the card, you’ll want to clean the gold portion gently with a soft cloth, then re-seat the card into the phone.


If the above steps do not resolve the issue, our Troubleshoot and Resolve Tool is great at fixing service issues of all kinds. You’ll want to choose your make and model, then Service/Network Issues – Phone calls, then follow the prompts within the tool.


I hope this helps out! Thanks for joining the Community Forums.
