B3+B5 combo is very unusual, maybe Xiaomi has it disabled in the modem configuration.
Actually, something is up with Telenor's carrier aggregation - I have the SIM installed in my phone, and SOMETIMES, when data is disabled, it shows CA B3+5 (my primary data is on Mobilink)

When I switch over to test CA on Telenor, the phone drops the CA signal and connects on one band only.

Mobilink would connect on both bands randomly, so I know it's not my phone.

Any one facing calling issue in jazz from past week? Suddenly opposite persons voice becomes distorted. Have to disconnect call and dial again.

Nope, not yet. Is this happening on 2G? Cause this is very normal on 2G ever since 3G became popular (it's just not as good)

Call connects in 3G. Might happen when it downgrades to 2G. Because this is where Jazz shits. Call drops to 2G from 3G during call and voice quality degrades

They all become horrible. Unless you're very close to a 2G tower (or have a good, clean 2G signal), you will hear a lot of garbling.

I don't know why networks throw you off 3G when a call is functioning fine on 3G - but they do. You could tell your phone to not use 2G via *#*#4636#*#* or some other service menu...but when you go to the outskirts, be prepared for no signals.

Jazz 4G+ in a residential area. I'm very impressed.

Peaked at 158 Mbps download speed.

Upload is quite disappointing though. Reason being that in this case, B8 (900 MHz) was the primary band and it was aggregated with B3 (1800 MHz). Usually it's the other way around.

The NSG screenshot showed the UL_CA: OFF flag which means that the upload wasn't aggregated and only B8 was being used for upload.

From what I've seen, operators around the world don't aggregate the upload channels - it's because the focus is on the downstream.

That's still very good though.

On Youtube last night, I was checking that Zong's managed to pick up their speeds as well - I'm interested what other PGers experience with Zong with screenshots of actual speed tests.

Edit: Zong is making their postpaid packages more expensive, FWIW, effective July. And Telenor has made it cheaper...ish.

Ditched Telenor for using their data. Complained them hundreds of time but they simply don't ever bother to even listen to your issues. So went to Jazz franchise and bought 4G sim and I was impressed that this is the speed I'm receiving on average now. Pretty dope.

You talk about poor speeds? They should fix their signals in the first place because where they have their towers, unplanned constructions, billboards, buildings and other things have popped up and these guys won't bother fixing it. Developed countries don't place their towers high up in the sky to avoid visual pollution, and even if they do, they try to camouflage it so that the city's landscape isn't disturbed - so I can understand why they have their towers lower down. But the side effect is that their antennas get blocked regularly.

And when you have a company that doesn't give two hoots about their signals/coverage and their quality of data speeds, well - this is what happens. They are already the second largest because they tapped the rural market first when others didn't, and only recently has their focus shifted towards the urban market.

VoLTE? Yeah, on one phone, I believe. They say on their Twitter feed all phones that support 850Mhz support VoLTE. In books, maybe, but not on their network.

I complained to them that there are a few spots where their signals are weak, and another place where I mentioned you enter a dead zone. Apparently, it's either "the best we can provide right now" or "the tower is down and maintenance is underway"... for over a year!

The only two good things? (1) when the pandemic came up, they announced on their website that PTA is asking for the customer data, and that this policy is applicable to all telcos (no other telco had this disclaimer), and (2) you can use 3G data whilst on a call.

Otherwise? Well... carrier aggregation rarely worked (it did once upon a time, and the same is with Jazz, but it doesn't work), so you get speeds of around 1Mbps when you could be scoring way, way higher (combined with the fact that their towers are a bit on the lower height). I ported out to Zong today, sent the request in the afternoon, and I got booted from Telenor's network in the evening.

And lo and behold! I have something for you all to feast your eyes upon! Do you see the 3x CA for Zong? I don't know what the combined spectrum is (I know it's definitely 30Mhz cause 1800+2100 = 30 Mhz, but I don't know what's up with the third 1800Mhz segment).

1595436992991.jpg

Couldn't test speeds since the new SIM plan stuff only permits 2GB or so from midnight till 7 PM (and it was 8.26 PM).

And this is in Bahria Phase 8. Most places have 2xCA, but this was the second place which had 3xCA, and it was near my home. I don't get anything inside my house since we live in another forsaken place where there's a lot of unplanned tall construction obstructing phone towers...

According to FAB's latest frequency allocation table which was updated some time in 2020, Zong's total spectrum in 1800 MHz is only 16 MHz. How are they getting enough spectrum to do 3CA?

I remember PTA gave them an extra 6.6 MHz temporary assignment, which would bring the total up to 22.6, but the new report by FAB shows that the 6.6 MHz previously assigned to Zong is now empty and un-used. So they're either clueless as to what Zong is up to, or this is some shady off-the-books deal between Zong and PTA.

Zong does very shady things, PUBG works for some on Zong, Unregistered Handsets if used with Zong SIM throughout works.

Yeah, I've been wanting to check out the allocation but the data on Frequency Allocation Board's website isn't entirely the same as what's available on the net - which says Zong has about 22Mhz in 1800Mhz.

But I don't get the 2100Mhz spectrum stuff though - can't find it anywhere. It has improved their throughout significantly though even inside buildings where Mobilink fails (although it depends where inside the buildings you are).

Fixed...... can't wait to use Zong 9G though.
Oh man! You should have kept 9G on there!

Btw, now that I ported back to Zong, I wanted to see if they're using the full 10Mhz for 3G speeds - there's really no way of knowing but I guess not since my 3G speeds weren't exceeding 3 Mbps in one spot that I was testing, and I wanted to test it in another place but couldn't... maybe tomorrow.

But their 4G speeds have dramatically improved where I wasn't getting decent speeds (indoors). I just have to test them out in Bahria Phase 4 if the carrier aggregation has made an impact.

OTOH, Mobilink speeds have begun dwindling especially in places where their signal quality is crap since their network isn't enabling aggregation all the time. I think if Zong continues to do what it's doing, they might launch VoLTE first (all conjecture, mind you). I'm honestly impressed with Zong now since they've caught up (at least in Rawalpindi and Islamabad) with Mobilink's average speeds; I haven't tested Zong out in the open where Mobilink gives 50+Mbps.

One major drawback of Zong right now (apart from more expensive bundles): they're having issues with pings - the same exact issues Mobilink was having once upon a time... but since I'm not a loyal customer, they won't give enough weightage to my complaint.

This is going to be a predominantly pictures-only post, with captions.

Zong, both bands aggregated. Check out the download speed on the top right. But also check out the poor pings.

This was the signal strength at the time:

Screenshot_20200725-185404.jpg

Can't upload the final image (it says it's too large) but upload speeds were around 9Mbps.

And in Phase 4, carrier aggregation appears to help Zong overcome the slow speeds, barring the poor pings. And 3G is restricted to 5Mhz since I couldn't breach 10Mbps (the poor pings result in download tests to ramp up slowly, oddly), but the speedometer didn't go beyond 1.5MB/s on great signal.

@shaheerk

Since Zong only has 10 MHz of Band 1 and they seem to be using all of it for LTE, their 5 MHz 3G is running on 900 MHz then?
