Ipoh coverage so so and Kampar is almost non-existence.

It's not something new that U Mobile had terrible coverage out of Klang Valley.

Calls should be fine. They had spotty 2G coverage.

I've been in Ipoh few days ago, travel around the town area. So far consistent on H+ , smooth surfing internet without any problem. I'm not sure how's those Kinta area as I don't have chance to reach there

you should get a prepaid sim to test things out first, if it works well then go for it. (better do it before 31st dec, because you can get 1gb every single month as long as you keep ur number active)

Ipoh coverage so so and Kampar is almost non-existence.

There are more hotels for sure it's just that they don't post it up online

Let me share my experience. I travelling a lot due to my work nature. I changed to U mobile P70 since 3 months.

Southern Region - N.9(Pedas, Linggi) : GPRS, Edge
N.9 (Seremban, Senawang): H+, 4G
Melaka : city area, H, H+, 4G
Johor (Muar, Batu Pahat, Kluang): 3G, H, H+
Johor (SKuadai, JB) : H+, 4G
East Coast Region - Kelantan ( Kota Bahru, Kuala Krai, Gua Musang) : H+
Terengganu (Kuala Terengganu, Dungun, Kemaman) : H+
Pahang ( Bentong, Temerloh, Mentakab, Kuantan) : H+

ps: I must said during travelling to east coast, except reach the city or town, basically the phone line is showing G/edge all the time, compare to my colleague using maxis. But even maxis is showing H+ and 4g, the line are fast as fast we expected.

Northern region : Ipoh (ipoh city, ipoh parade) : H+
I dont have chance to travel to northern part after I changed the plan. Will update once I got to there

now UMobile is on par with the 3 major telco, thanks to MCMC
