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?

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

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 just tested again. This is my test with single sim (Digi)



This is my speed test again after I insert in a 2nd sim (Yoodo)



Mine it's really bad. 😭

And taken out again, have another speed test.

My Battery level is 100% after 5 months of usage though.

I’ve tried having a clean empty phone on ios12.1.4 thinking that it will solve the issue. But no, still persist.
T&L hasn’t reply my email regarding this warranty yet.

Hi All,

T&L was giving me alot of questions and workarounds that I’ve done already. And seriously, their reply is really slow. Each email reply takes almost 12-24hrs.

So, I was impatient, and log in an appointment call with Apple support. They called back, and they were mentioning there’s none of similar cases happened before. So, on the call, they ran a diagnostic check, and found no issue.

But, the support guy is really friend and help to check if the HK device is serviceable in Malaysia ? And the answer is YES.

So, I’m going ahead to Maccity 1U later to have this check.

For the questions that T&L buyers here, our phones are serviceable in Malaysia.

But, my first impression of T&L warranty support is not good.

Will update again after my visit with Maccity

Remove 2nd and retry

Just handed in my HK set Xs Max 64gb to Maccity. They tell me that I wont be getting a physical dual sim replacement. As it is controlled by MCMC. So, yeah, my warranty experience with T&L phone.

Reason I'm ok with it, coz Maccity provided a loan phone, I doubt that T&L will loan a phone to me in this replacement period

You'll have to read all the previous posts, haha.. I had network data issue when using 2 simcard. And Apple support noted that mine is the 1st case in the world.

Yeah, nice of them and a loan phone.

An iPhone 8

Finally, got my replacement XS Max back.

MacCity handled the warranty. And initially, they gave me some issue saying that my phone (T&L) is a China Unicorn unit. They can’t process the warranty. It is only accepted for China Mobile.

After talking to Apple support again, and requesting Apple to make this warranty. They did as what Apple told them to.

And I’m unsure if this information is true. The technician mentioned that China Unicorn models have different bands compare to the rest of the world. So he is suspecting why I’m having the slow data issue. Which is not compatible with Malaysian bands.

Short story, Apple replaced me back with a local MY unit. E-Sim and Sim. I don’t have Maxis to try on the E-sim. So I can’t report back if my problem is still lingering on this new phone.

Nope they didn't reject outright. But called me 2 days later to reject. Before I send in, I have already confirmed with Apple that MacCity can handle the warranty

HK or China, I'm unsure. But that's what the technician told me. I may truly got a lemon from T&L at the start.

Apple replaced me a Malaysian unit, as MacCity again told me that MCMC did not approve the dual sim phone in Malaysia. And I won't be getting the HK unit back

Iphone dual sim per se

I did reach T&L, they pushed it back to Apple as they mentioned it can be claim locally. Only they mentioned if AASP give problems, they will step in.

IF HK set, then send it in for a replacment. If not, still send it in for a replacement. Just get a new phone. You paid for the price, shouldn't get these kind of quality.

But show them the proof.

Yup that's me. New set reception is flawless now.

They replaced a MY Set and using a single normal Sim now. Digi have not rolled out the e-sim yet. No chance to try it dual sim. And Yoodo still hasn’t allow me to convert my existing Yoodo number to an e-sim.

But, from usage, I can attest that my reception is way much better than my previous unit. I got a lemon I think.

I'm reporting back on my replacment phone to MY SET. Now have problem adding E-sim as a 2nd line. Previously was HK set.

I don't have an option to 'add cellular data' in my settings.

Apple seems to know this issue, on replacement handsets. This 2 sim iphone is not working for me. Almost 9 months, I'm still having issue with having 2 lines.
