Failed to unlock E583C huawei

[ctsintat]

Hi, I purchased some credit to unlock the E583c.

But got an error code 21, and modem failed to unlock whereas my credit had been deducted.

Any help would be greatly appreciated.

Regards.

Be sure you use latest dc-unlocker software version.
Check, if modem is detected by autodetect.
Check, if the connection software for this modem is closed.
Check, if not other huawei modem is connected.
Check, if not other huawei modem drivers were previous installed on computer you are doing the unlock. If were installed, remove all drivers and install only drivers for modem you are unlocking.
If this does not help, after error open device manager and update the modem device by drivers from modem. Then restart computer and do unlock again.
If that does not help, try unlocking on other computer.

Unlocking again same device does not require credits. You can unlock it without credits again.

With unlocked modem you need to enter your new provider connection settings (APN, username and others).

Try to check in router manual.
