I will be navigating by using an iphone7. I have ordered a T-Mobile sim card for this unlocked phone. T-Mobile has cell coverage through Telifonica in Colombia, Ecuador and Peru, Supposedly? Last year I just bought sim cards in Colombia and Ecuador and they worked but it was a real pain going into the providers office and getting service set up after I got there. Now, assuming I have some cell coverage I would like to enhance my maps with Google offline maps for use in navigating since I will most likely be in areas with little or no cellular data.
Anyone have advice or have used google maps offline for this purpose?
I have a week before I fly to Medellin.
Thanks
