Traveling to Japan - How To Avoid Roaming Charges
okay in 2weeks i'm going to japan with my mother. my grandmother is the one who pays the phone bill for the family although i do send money that covers my part. i want to use my iphone for the camera to take pictures in japan and occasionally use Wifi only . i already plan to turn off data and all that but i dont want to charge my grandmothers bill at all including costs for calling and texting internationally .
i read that if i keep airplane mode on (while enabling wifi still) that it should be completely free of extra charges since i'm not recieving and texts or calls and i'm only using wifi (when its available). i just want to know forsure so that i dont find out about a ridiculous bill when i get back .
sorry ive never traveled internationally i really want to know before i go !
