My brother gifted me his tecno cx ,that he was using,when I wanted to insert my SIM the phone ask a question relating to if I want the sim to bla bla bla with the phone yes or cancel.

I just hit yes without reading the query.

Now my brother messenger SMS is seen by me... His download pictures is seen by me. Atimes my download pictures are not found,i suspect he delete them from his phone too


Because the phone is dual SIM I try to add another SIM to see if the query will be asked again. It didn't.


How do I over come this because almost all hIs private text are seen by me and I don't know if he is seeing mine.

At first it was fun but is boring I don't want any messages from his side. Is like we are bugging eachother how do I correct this
