well if you're traveling do it my way
get a second or even third phone so you could see which service provider is better
on the location you are visiting.. and having more than one phone
can save you and keep you connected specially on emergency situation
where you drain your phone battery and you cant get to charge your phone
dual sims are good too but it's still better to have a spare phone like me
i have 4 phones, i always bring 3 when i go out..
