Too many users on that area. I manage to hit 20Mbps on 3G half a year ago but now most of the time hovering around 3-4Mbps on 3G

yup R does mean for internation roaming, but in this case, data roaming R showing umobile ROAMING ON maxis 2g network while u can't get any 3g / 4g of umobile, so just put the DATA ROAMING ON for ur phone to get this EDGE/G working 
for prepaid or postpaid ?

postpaid then might switch with me with great discount 

there is no any extra benefit between member and principal lines

but both of them enjoy per day 30 mins free call to any U mobile numbers after the 50 mins free call utilized

I do provide nano blank sims, but for printed prepaid New number then no choice mush cut it as Malaysia still not yet ready Tri-size sim like Thailand

only mini-micro , or nano instead of Mini-micro-nano
