Continuous CME error 701

Hello,
I am facing the issue of CME error 701 on uc 200T modem.
After updating the firmware of uc 200T modem(beta version received from quectel team),it worked for almost 15-20 times perfectly and i was able to download the .bin file from server and read it. but suddenly it started giving me 701 error continuously.Can anyone please help.

Dear Bipin,
Thanks for your inquiry in Quectel forum.
For your issue, it is better to provide the whole test AT log which contain the AT command you have entered. Then we can help to confirm where have the issue. Thanks!
By the way, beta firmware just can test the basic function, you’d better to contact with the guy send beta firmware to you, confirm whether the firmware you get have any special test requirment. Thanks!

Dear Bipin,
Please note that the following explaination about the command AT+QHTTPREADFILE. AT+QFOPEN is to open the file which already stored at module memory, which AT+QHTTPREADFILE is to read response from HTTP(s) server via file. They are not directly related, so it will get error code. Please note. Thanks!
