Traveling to a resort in Mexico, which does have wifi. My question though is with my Ting Android V1 network plan, if I enable International Roaming And Calling, does the Roaming part roam automatically while we land and transit to the hotel when my phone is on? Do roaming rates add up if it is enabled even if I don't use my phone and/or have it on airplane mode? Should I just turn off the international roaming and just have international call/text enabled only when in transit? I need the International Roaming only as an emergency. thanks! Not very phone savvy! I do use Whatsapp and skype on my phone for emergencies.
