Is it possible to bypass the OPSOSA restrictions on distribution using Mikrotik?

Question

Mikrotik

Good afternoon.
I want to bypass the restriction on the distribution of the Internet via Wifi.
As far as I understand, the task includes two problems:
1) Set IMEI on the device, which will be identified as a phone.
2) Fix ttl so that it does not change during distribution, no matter how the traffic goes, from the device where the SIM card is installed or devices that are connected to it via Wifi.
I coped with point 1, I registered IMEI from the phone on the ZTE920.
The second point raises questions. Now I have a ZTE920 on which it is impossible to modify the TTL and Mikrotik router. There is a plan to set up Mikrotik to receive Internet via Wifi and distribute it via Wifi to other clients. At the same time, it is hard to set the TTL on the Mikrotik router with the value ttl+1 from the value on the ZTE920.
Well, before starting these procedures, I would like to consult how viable this scheme is?
PS i.e. Internet operation scheme:
INTERNET<->(LTE)ZTE<->(WIFI)Mikrotik<->(WIFI)Clients

Answer 1

Mangle, change ttl. What is the question then?
