I have a Canadian LG K210 (LG Power) phone that was unlocked by the carrier Telus which I was able to use in Malaysia (for data and calling) and Thailand (calls only). Here in Taiwan, neither seems to work.
Here is the phone: K210 Canada info
It says:
GSM Mhz band Quad-Band 850/900/1800/1900 Primary 2G network GSM 850/900/1800/1900 Primary 3G network UMTS 850/1700/2100 Primary 4G/5G network LTE Cat4 700/850/1700/1900/2600 (Bands 2,4,5,7,12,17) Primary data network GPRS, EDGE, UMTS, HSDPA, HSUPA, HSPA+, LTE
And this is what I found about the my carrier Fareast One's bandwith in Taiwan:
Frequency Bands GSM Name Interface 900 (E-GSM) GSM 1800 (DCS) GSM
UMTS Name Interface B1 (2100) UMTS Supported UMTS Protocols Name Generation UMTS 3G HSPA+ 3.5G (4G speed)
LTE Name Interface B3 (1800 +) LTE B28 (700 APT) LTE Supported LTE Protocols Name Generation LTE 4G
I am seeeing some overlap with the numbers but not sure what I should be looking for as there are three other carriers I could switch to listed here: other carriers in Taiwan
