yes, I am from Indonesia, the reason may be wondering what does not work?
TKDN issue. Search for local news before askin in global forum. All devices that has 4G/LTE capability need to comply with minimum local content requirement. If the minimum local requirement is not achieved, the 4G/LTE will be lock by software. All other phone also like this, but in their case it can be opened easily using code. Xiaomi can't, they obey the regulation and make it difficult to enable it without changing ROM from Global to China, or patch the teleservice.apk or by rooting and editing the build prop file.
Kudos for Xiaomi for that, they show commitment to follow the regulation.
In summary :
- 4G LTE enabled for all old devices before Redmi3 : i.e : Redmi2/Prime + Mi4i
- 4G LTE disabled due to TKDN regulation : Redmi 3 Prime + Redmi Note 3 Pro
- 4G LTE enabled due to achieved TKDN regulation (phones are assembled locally) : Redmi 3S Pro + Redmi 4A
Other phones I didn't list as they were never released officially in Indonesia.
