i notice my iphone gps sometimes do not work. Depend on area to area. Midvalley mcD/carrefour area gps do not works. No gps icon. Once i step up to higher level (MPH area) the GPS only works.
Weird case, anyone encounter such issue?

please explain in detail?

what plan are you subscribed to? 1GB?

Try to do some research and get from MEP(s). 32gb stocks are out there. When the sign says "sorry no stock". Don't believe, ask the sales assistant in the shop.

iValue Simple. Yeah its 1GB.

Let me put this time line right:

2012/12/21: signed up iValue Simple 1GB Plan with iPhone package

*bill cycle: 5th? 7th? of the month?
if 5th: meaning to say 21st to 5th will be approx 16 days, prorated will be 16 of 30 days = 53% of 1GB = 530mb allocated till 5th of Jan 2013
if 7th: meaning to say 21st to 7th will be approx 18 days, prorated will be 18 of 30 days = 60% of 1GB = 600mb allocated till 7th of Jan 2013

2012/01/02: received maxis sms saying u used up 80% of prorated data

*this sms tells you that you have used up 80% of:
if 5th is the cycle date: 530mb i.e. you have used 424mb, and you have 530-424mb = 106mb left of free data to use.

if 7th is the cycle date: 600mb i.e. you have used 480mb, and you have 600-480mb = 120mb left of free data to use.

Now here's the thing: if maxis tells you that you have 100mbs left it's probably true.

I assume it's maxis tell you. if it's 100mb you 'assume' you have, which i think you probably monitor it using the general settings within iPhone, maybe you assumed u have 1GB of data till 5th or 7th? then you probably would have used up 800++MB of data.

that's why the unbilled amount reflects the excess data you have used up. better check with Maxis. Tell them you don't know. maybe can appeal to waive it this time. hehe

i experienced this once. got charged a lot of money for excess data. now the safest is i pay for the biggest data plan. at least i know i won't blow the quota.

I hope this answers?

U r trying to use gps in a building???

U need to see the sky to get gps signals. Satellites are in the sky

the problem is my friend s3 can get gps signal, but i can't weird

S3 using agps ?

Try using waze.

whateva what gps, as long as the phone support gps lol
yet I found surf china website or use china app drain a lot data

Hey guys! I ported over to Maxis recently when I bought my iPhone 5, so because it's been less than 6 months, the guy at maxis center told me I need to pay RM300 on top of showing my IC and passport in order to open my line for roaming overseas. Is that true? If it is, I think it's pretty ridiculous because I need to open 2 lines and am just going to Singapore for 2 days, then I need to pay RM600 in total?? Just for opening the line for roaming???

RM300 is standard rate to have roaming. It is a one time payment n maxis don't care how many times you use roaming. This is refund if you close maxis account
You can ask to waive this if you can proof with receipt any previous roaming agreement you have with other telco

as long u have wifi or celular data, phone coverage, and gps chip, then you can use in tower but of cos it will be not accurate inside building cos the system using cell phone tower to calculate ur location , then lock down to small area then only use gps to lock ur exact location then only use wifi/celular data to download the map in your area.

did u enable WiFi? WiFi helps!

but normally without wifi you will have good signal as i believe GPS has the best signals with the cell towers and wifi signals providing better triangulation details

hmm i tried without wifi and it takes significantly longer to locate itself on google maps.

for sure the data needs to be on to load the maps lor

correct me if i'm wrong.

i tried wifi and nothing happen too.

Mine register on 14/12 with iValue Simple..But until now still cant check data status..(You current mobile internet usage is not tracked..

bro, don't expect maxis to fix that itself. it will never.
i registered the same day with my friend. hers cant check until now. i can check mine from the first day. (been 3 weeks we getting the plan)
have to call maxis up to fix this.
