Are connection profiles reset in a strange way in the phone?

Question

MTS

Phone: Samsung GT-S5230
Operator: MTS
Periodically (once a month somewhere) the default connection (browser profiles) from MTS Internet to MTS Wap is automatically reset for no apparent reason.
In this case:
1) If you delete all connection profiles and leave only MTS Internet, then over time MTS WAP and MTS MMS connection will appear again, WAP will be selected as an active profile.
2) If you leave everything as it is (do not delete anything), but only select MTS Internet as an active profile, then over time everything switches back to WAP
In this case, the phone worked in normal mode. (did not turn off (the last 5 days) and was all the time in the home network). Also, when new browser profiles appear, it appears by itself (no SMS comes, no notifications), and this has been happening for about half a year. Maybe someone met with such a problem? And while you notice this, you can manage to lose 20-50 rubles.

Answer 1

have you tried creating your profile? and delete the default ones. well call it something else

Answer 2

I tried to create my own, and the rest deleted everything. They still reappear. and WAP becomes active.
I even tried to change the WAP profile configs. Still, he is recovering.
This whole glitch happens about once a month, sometimes less often

Answer 3

I looked through everything in the Internet assistant - there is nothing specific. Unless the service was connected - Access without settings. Now I've turned it off just in case.

Answer 4

The operator messes up. And the SIM is probably red, with an egg? The old yellow ones didn't. Try to come to the office and replace the SIM card, asking for a new one without MTS-Info and built-in applications. They love doing things very much.
