I need to make a choice between keeping my HK mobile number with SmarTone vs. moving it to 1O1O. I have accounts with both carriers, so admin is not an issue.
I'm guessing mobile data speed is comparable between the two networks, and so is the cost of data roaming (I have best experience with daily unlimited data plan for HKD 168 a day, or similar). Voice and texts do not matter either - it's 2015 :-) So, it's down to (1) coverage and (2) Customer Service performance.
Any suggestions?
