Iphone 15 n 15+. Another iPhone 15 n honor phone were working fine for tiktok. Weird.
Switch to ZYM then it work fine

becoming more like M1 for quite awhile, aggressive throttling with spinning wheel. did the M1 engineers already parachuted over..

they didn't need to parachute. They just stroll in, la kopi with Simba engineers at the same canteen and introduce themselves to each other.

Now simba got alot trolling about speed thought only exclusive to Eight

i was facing the same issue when in HangZhou, using Samsung and Honor. I thought it is because of Honor, but my Samsung was a problem too w/ TT. Happening with both Simba and Eight simcard. I didn't have Zym.

i barely kissed 50gb. if watch streaming, need to midway change to singtel it instantly stop the spinning. then why topup it? reception is not equal to throttle leh.

Full of lan zao shu from keppel. Every few secs throttle. Every few secs throttle.

Why not simba half the given gb instead, restore back to original.

Not tested with eight, but my test shows SIMBA China roaming is okay with TikTok.

I also had no issues using CUniq and giga data eSIM with TikTok either in China.

I was using two Poco X7 Pro phones.

Take note that I do not really use TikTok so it was just a brief testing.

One idea: if you have issues with TikTok, try to remove its access to location, not so sure if this helps though.

Time to port, not everyone is suitable for Simba or others etc.. trial and test till you find it suits your needs.

I do not need multiple lines as well.

Let me repeat one more time

Connected at 5G (no wrong doings here)
Cap speed at 4G or less (who can verify?)

If the following is correct, SIMBA limit 5G download speed to about 204 Mbps.

Take this kind of limit may not be super accurate so you may get slightly higher than 204 Mbps download occasionally but not much higher than 204 Mbps.

StarHub uses non-standard QCI values on their network, so QCI 140 is actually one of the lowest I've seen on StarHub. However, since the priority of different QCI tiers can be customised by the carrier, I don't think anyone other than StarHub themselves knows which order their custom QCI values (140, 150, 170) are in terms of priority. From what I've seen the QCI values also change depending on if you're connected to 4G or 5G, as the QCI for MyRepublic SIMs on 4G appears to be 150, while it is 140 on 5G.

Updated with some new plans I've gotten to test and the AMBR (speed cap) values which I have gotten from Network Signal Guru. Format is Download/Upload in Mbps, and numbers differ between 4G and 5G for most plans. Keep in mind the limit is unlikely to affect true performance, as most are well above what our networks are capable of. The only ones that may present limits in speedtests are GOMO's 1000/150, ZYM's 2000/100 and SIMBA's 204/204, as each network is theoretically capable of higher downloads for GOMO and SIMBA, and higher uploads for ZYM.

The acquisition not yet approved by imda, m1 staff how to work at simba?

Different location, and now it's happened again.

I was making a call from my Simba line (primary line), except that this time the data usage is set to Simba (previously Eight).

For record, Simba line shows 2/4 bars on my iPhone while Eight shows 4/4. The latter looks better, right?

While making the call (on speaker so I was able to observe the screen), the Eight line went all the way down to 1/4 bars.

This could highly be the reason why my previous call from the Simba line was cut off, when data usage was set to Eight. Simba calls need VoLTE, right? So when the Eight line went down/off, the call got cut off.

Does that mean I've to 1) use only Simba line for data usage, or 2) port this primary line out to another telco that doesn't need VoLTE for calls, so that I can set data usage to other telco lines as and when I like?

All the telcos need VoLTE now, unless you are lucky to have 5G SA coverage and working VoNR at all places you go, which is not possible as of now. Or you stay home and use only VoWiFi, which does not seem to be applicable to you.

Just give up on using SIMBA as the main line. Use it as a secondary line and also for roaming.

Thanks, I guess that's my only option for better line connectivity.

By right this should not happen, it is very weird. The beauty of 4G is that both call and data will still remain active and not sacrifice either. May be it is the phone model operation oversight of proper dual sim function? If you try to use it as single sim by removing your Eight sim card, will the problem remain? If it functions well, may be 2 phones for each sim is the way to go, or change the phone with proper dual sim operation?
