I have a bit of problem. One of my clients regularly get locked out from his LTE provider account and can not recharge it with prepaid home Fixed LTE-A when locked out (password incorrect 3 times). The reason for this is when a person registers for the service you can no longer use GSM/2G/3G. It is pure LTE/LTE-A with no fallback. The OTP to reset the password get MMSed to the sim in the device but it looks like Mikrotik devices can not store MMSes only SMS in the SMS inbox. When I request an OTP the log shows the device is receiving a message but nothing is happening in the inbox.
I did try sending a SMS to the device with a normal prepaid sim and the devices did receive the SMS in the inbox. When I tried to send a MMS to the normal sim it showed it receives a message but nothing in the SMS inbox. Is there a way to make Mikrotik device accept MMSes thru some plugin. This is frustrating due to that the device is high up on tower and every time I have to go up there and take out the sim to put in a phone so I can get OTP MMS.
