Avoid paying for International Roaming when you travel.
When using RoamHero Follow-Me, you won’t miss calls to your HOME SIM phone number even if you take it out and put in a Local SIM card. Your calls will be routed from your home, through the RoamHero cloud and to the Local or Global SIM card that you are using. (Hint: compare RoamHero Follow-Me rates to your carrier’s roaming rates.)
Make sure your phone is unlocked. See how to unlock my phone.
