Thanks you.

Attempt to perform these steps:
Try dialling up again. This error is usually only intermittent.
Retype your username and password into the connection box, even if they seem to be okay.
Ensure your connection is showing the right dialup number.
Set up the dialup connection again.

Can not connect to 3g or edge or gprs or any

Hi, I have completed the steps above,

I tried the modem with multiple chips, all detect the type of GPRS signal but fails to connect to any network.

I have tried to connect with the program that brings the same modem and windows, without any result.

This problem does not usually happen in the first modem unlocked.

Please look at the attached images.

We won't be able to check much from screenshots since they are not in english. Check settings that you use for device connection to another operator, make sure it is set to automatic and not set manually, check apn settings too. Test modem with its original sim and see if it's still same.

Hello,

As mentioned earlier and I auditioned with several operators,

All detected but no signal network allow me to connect.

Please let me know if you can even put another version of firmware.

Urgent need my two modems functional

Thanks for your solution to this problem.

Thank you.

There is no guarantee that it would work.

Hello,

Because it is a problem in your software,

Could some please give me a account to use this program ZTE ICERA Firmware Writer for my two modems?

Thanks for responding.

This is not related to our software if one modem works. ZTE ICERA is not usable with any account it requires dc-unlocker/rocker/vygis or infinity dongle connected to pc, otherwise software simply won't launch.

Well I have nothing more to do but open a dispute in Paypal by this problem.

Thanks for your support.
