Guys, please help. I accidentally bought a Xiaomi Hongmi TD-SCDMA version back to Malaysia and I found out it unable to use in Malaysia GSM card. Want to ask: - Will it be able to change the bandwidth TD-SCDMA to WCDMA so that I can use my 3G service in my country? - I try to slot in both slot (the TD-SCDMA and GSM slot), the phone seems unable to detect my sim card even i try few other SIM cards as well. Is it because of the phone or SIM card problem? - I found out that the IMEI number is unavailable. Is it the root causing the phone unable to detect my SIM card? Please help.
