which malaysian telco provider is supported?

i checked wikipedia info for celcom, it seems like their frequency bands do not match the above exactly. meaning i can only use this antenna at certain locations where celcom uses the supported frequency bands?

900 MHz (890~905,936~950) 30 MHz GSM/UMTS
1800 MHz (1735~1760,1830~1855) 50 MHz GSM/LTE
2100 MHz (1950~1965, 2140~2155) 2 * 15 MHz UMTS/HSPA
2600 MHz 2 * 10 MHz LTE
2600 MHz 2 * 20 MHz LTE

Celcom

Thanks for the reply.

I'm interested to know if you actually got any signal strength improvement while using the antenna. I used my friend's antenna (same model i think) and saw absolutely no change in signal strength bar between using the antenna and not using it. When i asked the seller, he mentioned that maybe the telco is using frequency bands unsupported by the antenna. That's why i asked you this question...
