I got a blackberry. with a CTM Macau SIM. Their roaming charges sound too good to be true.
Roaming for Thailand is 0.02 MOP per kB, for HK 0.01 MOP per KB. China is significantly more expensive at 0.07 MOP, still half PCCW's price.
By the way, CTI has a Bridge roaming data package for 5, 15 or 40 MB (Covers most Asian destinations except China). 40 MB for 888 HKD per month. But with a blackberry, used only for text emails, using WIFI wherever possible, even 5 MB is hard to reach. (Would cost me about 50 HK$ roaming in Hong Kong with my Macau plan).
I just want to wait for the first bill to see if the unbelievable comes true.
