Is there a different in prepaid and postpaid internet speed?

Using prepaid and my sis using postpaid, her internet is more stable and fast than mine, switching sim card to test, confirm not my phone problem, any one facing same issue?

Erm, I don't think so.. but

1) Is both smartphone LTE (4G) capable?
2) Is the prepaid quota (High Speed Internet or Basic Internet?)
3) For reference purposes, what smartphoneS are you using to compare?

That is all the variables I can think off that may affect your internet speed.

maybe you already used up your high speed internet and currently on basic speed only. the only difference is because postpaid has higher high speed data than prepaid, so she still enjoying high speed ibternt while you are not.

Postpaid get more priority in peak hour than prepaid...

Tested myself using prepaid while my fren using postpaid last time. 2x same device and same cell Id base station. Speed just differen

You should try same device and make sure is same cell id base station.

Witness it yourself

if this is the case, no point people buy prepaid to test before subscribing to their postpaid. since it's not accurate lol...

1)yes
2) UMI 20 (1.5GB- now change to 2GB package)
3)Redmi Note 3 (snapdragon) and Meizu MX4, after i switch the sim card, speed work excellent, i think it's not my phone problem

the fact is UMI20 lower speed than all other plans, this was very old issue already

All telco got coverage good and bad in different areas, hence why everyone should spend RM8/RM10 to get a prepaid to test their commonly used areas.

On average Maxis and Celcom got better coverage nationwide. U mobile a few good areas (Subang Jaya, not USJ, is one, another is around their HQ in KL). Digi also got up and down depending area.

Digi a long ktm line mostly life can go lag , hang I try to redeem the free 8Gb can't haiz many should port back to umobile  really suffer  don't which to choose  digi klang vally okay

Hardly understand what u try t express.

I mean digi suck  know how do marketing but don't know how to improve network issue and customer issues

Digi is spending over rm 900mil on network upgrade this year

Well only some area..

some high traffic areas do face some issues.

overall it's good.
