Hello! I have the same problem. We have already discussed it via Skype. But the last days your employees are offline. We turned to operator technical support. We were told that there were no locks on their part. We also updated the firmware to version 2.4.6. We also tested the module with SIM cards of other operators. Of the four, only one worked. Perhaps this operator does not pay attention to imei. The problem is not solved. Can you help with anything else?
