Sun Cellular subscribers can now use Smart’s network to get a signal where the Sun “doesn’t shine”. Sun Cellular postpaid and prepaid subscribers just need to dial *247# to access the menu which contains instructions on how to switch to Smart’s network.
Here are two instructions from Sun Cellular for Android and Nokia Symbian phones:
Nokia Symbian:1. Menu > Tools2. Settings > Network3. Network Mode > Manual4. Choose Smart5. Return to Network Selection Mode then choose Automatic
Basically, you just need to do a manual network search on your mobile phone and choose Smart on the list. So if you’re using a different phone, say MyPhone, just look for the network settings and choose manual search. I heard that this will only work on areas with weak or no Sun Cellular signal.
