I just bought 3 new top end (for a SASSA pensioner) Samsung Galaxy phones and not one of them can receive or make a call around my house.
Samsung J4, A10 and A20. My last 3 ( <R1000 each) mobicells work well, giving 2 bars, and an 10 year old brick gives 4 bars signal.
I want to buy a GSM booster but need info so I can make an informed decision.
My question:-
I can understand the booster picking up the signal from the 1Kw tower 40 miles away on a yagi antenna , boost it and re-broadcast it on a dome antenna in my house.
What I do not understand is how it picks up my tiny Milliwatt transmitter, and make the tower 40 miles away receive it???
Thanks for helping an old pensioner.

I sent an e-mail to coverage@mtn.co.za, they had a look at the coverage problem at my house and eventually came out and installed one of these units at our house, free of charge.

It's connected to an external antenna pointing to a MTN tower.
Thanks,
I sent them lists of hundreds of missing calls an dozens of letters complaining that we can not be reached.
So far all i had was empty promises???
