As request, tested the U28 package at Penang Island, Relau area, one of the most crowded living area with many apartments and flats.
Penang is still limited with 3G/H+ speed only.
At some Relau area where signal is just moderate strong, the speed is as below.
Considered not bad as previously Maxis has very bad 3G coverage at this area (which cannot even send out chatting message, but Maxis neglect this issue by 4G coverage)
At the area with strong signal, almost full bar H+, the result is as below.
Consider this is pretty good on a H+ signal.
The data balance check do indicate real 3GB data usage.
Has also make the 1st phone call. Call quality is very clear and loud.
Has actually also tested at Penang Island, Bayan Lepas FTZ industrial area, the signal is very weak at most of the spot, only able to get "E" signal inside the building, and moderate "H" signal.
But, other telco signal also perform very poor at that area, so it is not a surprise, anyway.
1st impression on U Mobile U28 at Penang area: consider good, comparable to other telco coverage, just lacking the 4G coverage.
