Help: MTN Roaming is better than my Native Telkom Signal

[bromster]

So whenever I'm at work, my Telkom gets 1 or 2 bars of Edge. If my phone switches to MTN Roaming, I get full HSDPA signal.

Is there a way to tell my rooted Samsung S5 that I would prefer to use the roaming signal over the native Edge?

Yes just go into network settings and select search for networks.

Once it is done searching select mtn. It will now stay on mtn roaming.
