Hello, Clarkman!
As I see in Malaysia, these frequencies are used:
4G: B3, B7
3G: B1, B8
2G: 900 MHz, 1800 MHz
According to these frequencies, devices with the corresponding product code can be selected:
RUT230 * 0 ****
RUT240 * 6 ****
RUT850 9 *****
RUT900 S *****
RUT950 U *****
RUT955 T *****
RUTX09 0 *****
TRB140 0 *****
TRB142 0 *****
TRB145 0 *****
All these devices support operation at the desired frequencies.
As for the global version, many of the devices have such options, I suggest you go to the link below and get acquainted with them:

All options are there. Knowing the frequencies at which the router should work, you could choose the best solution for you.
