Umobile actually not bad if you used it only in Klang Valley~ been using it for about 5years already~ Only some places no line but this is what you get lo for a cheaper price...

if outside Klang Valley then I can understand there wont be much Umobile centre. I personally find it 3G is quite good already le~ I only started using 4G this year, past 3 years i'm using 3G only and I had actually turned off 4G purposely where I tot it actually drain battery faster. But with latest technology then it shouldn't be the problem. So I find 3G speed quite ok unless you are going to stream 4K videos. I only find 4G useful when you require to send and download large files, and stream videos and music. Otherwise 3G quite sufficient.
