I’m now studying of how to get national roaming with other operator. Our network is only 2G, but more coverage, while the network we want to roam to is 3G. Therefore, we want to roam only data call.
My question is that, after finishing the call on roamed network, how can we make the users come back to our 2G network faster? Is it related to EFHPLMN parameter? How do we set it?
okie, as far as I know, you cannot set this parameter, unless you have to order with SIM provider. They will set this parameter for you when manufacture the SIM
