I Switched to umobile mb128 plan last 2 months .. first 3 weeks my speed was absolutely rubbish until i spam called them 3 times .. all this 3 times they told me its gonna take 1~3 working days and just give me a report number which does ntg .. Until the 3rd week , my speed was finally 'something normal' .. but things get back to worse again after my first bill ... the speed throttle down back to 0.1 ~ 0.3mbps .. As i fedup with the cs , i just decided to canceled the plan ..

Unstable speed , Poor CS , Frequent disconnections (keep switching back to UMTS)

As my house doesnt have telephone line , thats why i decided to try umobile .. And from the first day was already slow like 0.3mbps .. imagine first day of subscription already got problem , havent even over quota .. if over ed then ?? ... All i know is , the speed is unstable .. Keep switching back to UMTS even with full bars =.=
