LTE radio frequency band by ipad is 700MHz sth like that, they are built in mind for US LTE users, not cater for asia. unless got other ipad LTE stock version.

ALL wireless technology use radio frequency band to transmit data.

just imagine radio, you tune to wrong frequency, u cannot get to the desired radio station .

imported car from japan using different freq also.. but yet still can receive local station

Car radio, e.g. FM Radio, is a quite standard range, 87.5 to 108.0 MHz
Japan FM is 76–90 MHz, unless the car-radio HU is designed for international market, which supports the full frequency range.

What LTE in US now is 700MHz. The most likely LTE in MY/SG is 2.6GHZ (2600MHz).
This is totally out-of-tune, chicken-and-duck talk, frequency is totally different, hence cannot communicate.
