I will be moving there soon so I'm looking to flash my device with a Singaporean OS so that I can make use of 4G. Anyone know if the SG devices are carrier branded?
I bought my gray 920 in Singapore completely unlocked, and I can use it overseas so far, so it is possible for you to get 4G there as long as you purchase the 4G sim card from a carrier. I hope that answers your question?
Unfortunately you will have to wait for an update from the Thai carrier that unlocks 4G connectivity since your 920 I assume is Thai specific model
