bro,

try change your setting. If using 2 sims, may be the default setting for your phone is only 2G.
If 1 sim phone, try chat with webe chat team in their website

I've been using webe now, from Meru, Kapar to KL, all the way 4G.
Back to Kelantan also 4G most of the time.

FYI, webe has their own network now, not tumpang2 anymore.

this is what my friend who work in webe told me lah
