said by WiFi:You will have nearly full coverage between Dallas and Abilene. Some places will be stronger than others, but that's the same with any carrier. If your phone is unlocked, grab a SIM card from T-Mobile and go prepaid for a month as it's still cheaper than the Canadian roaming rates, unless you are with WIND, then get their new unlimited USA coverage for one month.
I ended up grabbing a Roam card since it was on sale($15)
I'll just grab the $30 plan (7 days and 2GB of data) and take my chances on coverage between Dallas and Abilene. Next issue will be getting a car that I can physically use (disabled driver) but that's a whole other thread in another forum (though which forum here would be the one to ask questions about car rental agencies
)
