I have T-Mobile and the APN is set to the recommended settings found all over the internet. Roaming data worked just fine in Japan (Softbank and Docomo), but I dont have roaming data in the Philippines. Im currently in Metro Manila, connected to Smart, have a strong cell signal, but no data (! next to the bars). My sister has a LG G3 and she has data just fine. Is there a setting I need to change? Thanks.
