I'm taking my family on a 2-week RV roadtrip to Alaska later this month (we are from GA, and plan to stop at Anchorage, Homer, Seward, Kenai Fjords, Chitina, Valdez, Paxson, Denali NP, Talkeetna etc.). I've googled about T-mobile in Alaska but got either dated or confusing info. I called T-Mobile and was assured that my T-moble ONE will work just as it does in Atlanta--> i dont need to turn anything on, and all the unlimited talk and data will automatically work on the GCI network when i arrive in AK. Can someone with recent experience tell me what I'm up for:
1. Do i need to turn roaming on on my phone?
2. will T-mobile work in Alaska (understand that coverage can be spotty. but to the extent that GCI has coverage will T-mobile work?). is there cap or throttle or surcharge on my data/speed/talk (i've heard anywhere from 200mb to 5gb data caps)?
3. should i purchase additional add-on from T-mobile for this trip? the custy rep told me that for $15 a month i can upgrade to the ONE Plan Plus which comes with 20gb of high speed mobile hotspot data and can be used in Alaska just as in continental US. Is this believable?
4. Any suggestion as to what i should do for cellular and internet access for this trip? is T-mobile bogus for this purpose and i should just buy a prepaid package (From GCI/ATT) when i touch down in Anchorage? If so how do i go about it?
Thank you very much!
