Hi Guys,

A thing that I found out after 5 months use of the dual physical sim, XS Max 64gb HK

I will have very slow cellular data on line 1 (almost half the speed or lower) whenever I use 2 sim or 2 active lines. I have changed Umobile to Digi as my main line thought it was Umobile giving bad coverage. But both (provider) poses the same issue whenever I use the 2nd sim (Yoodo).

When slow it can go below 1Mpbs.

Speed testing on 2nd line has no issue. The data line of 2nd line is fast.

Tried on ios12.1, ios12.1.1 and just recently 12.1.4

After I remove 2nd sim from phone. The speed goes back to normal.

So I guess it's not firmware issue. It's a hardware problem. Anyone here faced this when using 2 physical sim?

both of the ios ver u mention is having some issue with the network connectivity.
I'm using 1 phy sim and 1 esim, no issue with my line. Btw i'm using ios beta 12.2

Thanks for the note. As I'm not on esim, hence I couldn't confirm.

I'm checking with some of the 2 physical sim users if they are having these issues. It was worst using ios 12 and ios12.1. The wifi also got affected with the earlier versions. Ios12.1.1 solved the wifi issues

I've tried two SIMs before on my HK XS Max, and both no issues with data speed. Primary Sim was maxis and secondary was Celcom. Could it just be a network issue?

It's not, when I remove 2nd sim, Primary Sim data doubled the speed. And you can see smooth consistent speed line on Speedtest. When 2nd sim is in, the speed line will be juddery.

So guess mine is faulty

I see. Let me try again tonight and will tag you on the results.

Battery case for XS now available

tempted....

Seriously bro, at that price?

the only problem stop me is almost every year i change phone else i am ok with the price since it is much better integration compare to third party

Dun go for new phone every year bro 😁 Maybe with the case can last > 2 years.

When change phone sell the battery pack to recover some losses lor

Tried with my wife’s XS Max using single SIM, maxis: -



And this was with dual SIM, 2nd SIM being Celcom. Speedtest on the same maxis SIM: -



So I don’t think a second SIM should slow down the data speed of your first SIM.

Faster with 2 sims?

Hahaha, I’m pretty sure that was a network thingy or coincidence

I guess 12.1.4 is having some issue with network itself.

I guess is IOS problems.


I'm using beta 12.2 beta 3 no issue with network with running two sim on my phone.

Hopefully we'll get 12.2 soon

Some clarifications on Maxis e-Sim as of today. Customers can only apply eSim if you do not have multi-sim package. The eSim is for single-sim package for now. They are still sorting out some technical issues (whatever it is) and will release "multi-sim eSim" in coming 1-2 weeks.

Next week i guess.

thats my annual KPI i pass one year old phone to parent/younger siblings

but could not fetch much i think... anyhow, my Xs lasted two days before i charge, so the power pack just not so useful, just saw the integration is good, tempted to buy and try lol
