I have a Motorola G2 dual sim, I have 1 sim from another network provider for internet and 1 Optus sim just for call and message (no data). Just a couple days ago, I have a problem: if I set 3G for another sim and 2G for Optus sim (for data reason) I have no signal with Optus sim, if I set 2G for another sim and 3G for Optus sim, I have signal with Optus sim but only get 2G for internet with another sim ( that's not what we want to in 21th Century ). How can I solve my problem ( I did use 3g for another sim and 2g for Optus sim before no problem).
With the closure of Optus 2G network this is what happens. Have a look at this link:
