Most of the persons who are spending 250K on a phone, will definitely visit foreign countries like Dubai, UK, Singapore etc where 5G is available. And there they can not use 5G on their phone just because function has been disabled by a software.

It will be enabled when they insert a SIM card from those regions.

Just like VoLTE toggle doesn't show up in Pak, but it shows up in UAE when I insert a local SIM card.

All well here. Thanks for asking.

Hope you and the family are doing well too.

RCS is the only exciting thing to happen in telecom industry in Pak since all telcos were dead before coronavirus and will remain dead for the years to come in regards to new features being launched.

The way you described it is exactly correct. It's nothing more than an instant messaging platform, but just built-in to the messages app.
Ain't better then to just use whatsapp bro [emoji1787]

I hoped a real sms - transition

Like sending pics/vids without data/wifi and real-time chat - not like mms, mms sucks lol

Or sending pics/vids with data/wifi to phones which don't have rcs enabled but are capable of handling pics/vids.. just to cut sms costs.. like sms over internet

But as you said , it only works with data/wifi to only those who also have rcs enabled, so just like another whatsapp .. thats disappointing tbh xd

Edit : Can we send messages to non-rcs (any mobile number) using just data/wifi without sms costs ? [emoji848]

Nope.

But I do believe if you send an RCS message to someone who has RCS enabled, but no internet, you'll be able to send it fine but I think (IIRC, based on my early tests) the recipient will receive it as a standard SMS.

So lack of internet connectivity is no reason for not receiving a message.

And naturally, when the other guy doesn't have internet connectivity, standard SMS rates will apply.

But otherwise, yeah, it's DOA and Google would have been far better off had they launched RCS during the early days of WhatsApp. But no, they chose to have 20 messaging apps during this time instead.

So Telenor does have CA Aggregation in Faisalabad. They are using 5 MHz of Band 5 and 3 MHz of Band 3. Since accumulated spectrum is only 8, my Galaxy A50 does not show 4G+ sign (samsung phones show 4G+ sign only at 20 MHz accumulated spectrum)







Update: CA only works early morning. After that it does not work. Don't know why.

CA works when it wants to work - completely random. Same with Mobilink - it wasn't working for the past few weeks but has been this week (and some random week in between as well). Telenor's only recently started working in Islamabad this week, I think.

I have no idea what's going on - I feel they're up to something at the network end.

One benefit for Telenor is that when you're on a VOIP call and you get a regular call, the VOIP call will continue to function since they allow data browsing on 3G during a call whilst the others don't. Otherwise, their speeds aren't exactly great especially indoors. I think they basically got lazy with the 850Mhz masts (they probably thought "oh, we can spread our signals so far away we don't need towers" - and here we are, their signals have trouble penetrating buildings because the masts are far away - but then, there are other instances where the phone clings onto a signal because of the way the antenna is positioned).

Another thing Telenor is doing wrong is spectrum management, which is a total mess up.

Their 4G users are now more than their 3G users. Still they are spending more spectrum to 3G instead of 4G. Icing on the cake they are using 2 different 5 MHz frequencies for 3G. So if some one is using their 3G, irrespect of the band, he will end up using 5 MHz only.

Thing they need to do is, stop prioritising 3G (atleast in big cities if not all over the country) and start concentrating on 4G. They should spare 5 MHz of 2100 MHz band for 3G only and start using full 10 MHz of 850 MHz band for 4G along with 5 MHz of 1800 MHz band. Their Carrier Aggregated 15 MHz 4G can somehow save their face untill they can grab some more spectrum in next auction. Since 5 MHz or CA 8 MHz is not helping their 4G at all.

4 MHz of 900 MHz and 3.8 MHz of 1800 MHz band is enough for 2G.

(apologies if the post is a bit haphazard - I had changed it a few times in the middle so it might have some loose ends in between, and 12.44 AM doesn't help much along with mosquitoes roaming near my face)

It was a poor business decision which they now have to stick with. I've used their CA 5+5Mhz in Islamabad/Pindi and honestly, you can get average speeds of around 20Mbps easily - provided the signal quality is good. The highest I managed to get was around 50Mbps, I think (I posted a speedtest in here).

As for why they're focusing on 3G: well - since no operator has broadly launched VoLTE, 3G is here to stay for the time being. In some countries they'll sunset 2G, and in others they will sunset 3G. I read initially Telenor will sunset 2G, but I'm now reading they'll sunset 3G and retain 2G (or maybe I read it wrong earlier). While I personally don't agree with retaining 2G (which is so outdated), the rural population don't have phones that go beyond 2G, where Telenor earns its bread and butter from primarily.

That aside, I think they thought "Oh, 850Mhz? Let's space out the towers even more cause the signal travels far" - so some will be on 850Mhz, and some will be on 2100Mhz. Good mix of signals and coverage. In theory. What suffered in the end? 4G. Then CA with 1800Mhz meant decent 4G (in theory) and mitigate the low speeds. But the trouble is their signals just aren't good enough everywhere for data speeds (but good enough for 3G voice, not 2G voice) because of the interference / concrete / angle / tilts. I know Mobilink overhauled their network for both 3G and 4G hence the fairly consistent speeds. Telenor probably employed NSN for some reason.

Anyway, past knuckleheads in Telenor took wrong business decisions, current guys probably aren't able to meet their revenue targets (I suppose), can't justify further investment in network fixtures, and thus, are basically trying to save their face with whatever they have and grease the palms of the Europeans. I don't think this is working for them, which probably explains why their ads have toned down and either I'm not seeing them at all, or I've stopped watching TV altogether.

Now since 3G is being sunset in 2023 (sources below), as you said, they could buy Ufone, allocate all of 850Mhz to 4G, shift some 900Mhz spectrum to 1800Mhz and make it 15Mhz 4G (sparing some for 2G), and carrier aggregate the two 4G bands together. 5+5Mhz CA is actually enough and better than 10Mhz contiguous, as CA ensures higher combined speeds vs. one 10Mhz chunk of spectrum - Google it! And if they buy Ufone, they can dispose off 2100Mhz altogether to save costs.

If they don't buy Ufone, they could repurpose their 5Mhz 2100Mhz to 4G and have 10+5 for 4G, and use 1800Mhz and 900Mhz for 2G.

But for the love of all great things in this world, broadly launch VoLTE so that there's reduced pressure on 3G.

That's not the (user-facing) problem with Telenor - if you stand next to a tower, you get decent speeds even on 5Mhz, so bandwidth, seemingly, isn't the issue - they appear to have enough throughput from the towers, even on 3G. The problem is the signal propagation through buildings, trees and construction, affecting 2G, 3G and 4G. They've got these hifi cloud systems and what-not going on internally, but damn, their signal propagation (and quality) is crap indoors.

Wait.. volte is in pak ?? [emoji1787]

10 years after ; when volte will broadly launch here ?

30 years ; k my bad it will be launched next year..

50+ years ; (from grave) i m getting volte signals now great .. ah nevermind im not alive anymore ..

500+ years : european excavation digging old ruins : Sir, we found a grave with a 21st century mobile phone in it..

Chief excavator : Ah, those must be the people of that country who died waiting for volte technology.. poor souls..

I strongly agree that Telenor made some wrong decisions in past which are still hindering in their way.
First they were absolutely wrong to purchase only 5 MHz band for 3G. They knew that 3G/4G is long due in Pakistan and Fixed line broadband situation was dismal in the country. So it was sure that all of the burden will put on mobile broadband. But they did not think about their customer base and future. And that decision still haunting Telenor.

Their second wrong decision was to purchase 850 MHz band for 4G. 850 MHz band was so unpopular at that time that only 5 countries in the world were using it and supported devices were not available in the market, and among 5 countries most of them were using it on CA with some other band. If they were in dire need of 4G spectrum they could have asked PTA to auction 1800 MHz band instead of 850 MHz since there was no other company interested to purchase more spectrum at that time. But since they were still thinking to improve 3G they went for 850 MHz because 1800 MHz can not be used for 3G. Or they can also had asked PTA to auction more 10 MHz of 2100 MHz, it could have impreove their 3G and 4G as well. But they preferred 850 MHz and this decision ruined their 4G future.

Due to restrictions friendly frequency, 850 MHz can not provide speed but indoor coverage only. If they are so concerned about 3G and can not offer VoLTE, they can use full 10 MHz of 850 MHz for 3G because with 10 MHz DC-HSPA+, it will strengthen their 3G instead of simple 5 MHz HSPA+.

And for 4G they can use 5+5 MHz of 1800 MHz and 2100 MHz. Their indoor coverage may not be as strong as now but they can offer much better speed with this 10 MHz spectrum (Jazz didn't have strong indoor coverage everywhere but works fine even with 2 bars). Zong is also ising these 2 band for CA.

Second option is they can opt for 3G closure as soon as end of 2021 and use all of 20 MHz of 3G/4G for only 4G services.


................................................

Apart from Telenor mess I think PTA and FAB were not fare in allocation of 900 MHz and 1800 MHz GSM spectrum. They alloted 7.6 MHz of 900 MHz to Jazz, Ufone and Zong but 4.8 MHz to Telenor and Warid. Now 4.8 MHz can neither be used for 3G and nor for 4G (3 MHz 4G refarming is of no use).
They could have easily made 5 MHz for both Warid and Telenor by deducting some points from other operators and they didn't even bother.

Similarly they alloted 8.8 MHz of 1800 MHz to Warid and Telenor when there is still some spectrum left after allocating 20 MHz to Jazz and Zong for NGMS and 6 MHz additional spectrum to Zong for compensation. They still can easily made it to 10 MHz so that they can properly use it for 4G.

But in PTA, FAB and Telenor, everywhere those people are sitting who does not have any idea about spectrum management and future planning.

Soooooo... I just got offered to activate RCS officially on my phone.

It picked my Mobilink SIM (and not Telenor). I don't think it even let me pick which SIM I wanted it on. But doesn't matter, I use Mobilink anyway.

I welcome myself to the party that started several years late. Thank you all for having me in here in this empty room where I don't know who to talk to (apart from the void filled by the operator spam).

They're all lunatics, honestly.

But a quick correction - the bands, themselves, don't determine the speed. 10Mhz 4G on the 850Mhz spectrum will give you the same exact speeds as 10Mhz 4G on the 2100Mhz (or even higher) spectrum.

Think of bands like the highway, and your spectrum like the car. I'm going to talk in analogies now: I think 850Mhz isn't a very wide highway, so your existing Corolla (10Mhz) cannot be upgraded to a Hi-Ace (15Mhz) even though will travel at 100km/h perfectly fine with zero difference because the 850Mhz highway isn't designed for big cars cause the lanes are meant for smaller cars, and your big car will take up the space for two lanes so the government won't allow it.

But on the 2100Mhz highway? You can use a Hi-Ace because it's a nice shiny 10 lane highway. Heck, you could drive an airplane with all the bling bling in the world because the 10 lane highway (2100Mhz) can accommodate such vehicles (spectrum), each side, so the government has no objections (permitting space constraints).

Hope this clears it up. One band has more available spectrum than the other, but the speeds of a Corolla on a 2 lane highway and a 10 lane highway will remain the same, while an aeroplane can't travel on a 2 lane highway because the space occupied is too much.

This is what is meant by "spectrum shortage" and lower band spectrum will always remain short because low band frequencies are narrow highways, while high band frequencies are wide highways (but they don't penetrate all areas and exist outside the cities - like the motorways, as opposed to Islamabad highway which cannot accommodate more traffic). This is why you can drive faster on the motorway if you have a car that lets you, and this is why 2100Mhz is cheaper (demand vs. supply).

Okay, time to go sleep.

Got the update today. Carrier is telenor. No idea why are they not advertising it. Though I feel it's pretty much useless at the moment if the other person you are sending messages too, hasn't got it enabled. Standard rates will apply.

Since I am a Samsung user and was using Samsung default messaging app, after seeing posts of all of you, today morning I side loaded Google's message app and make it to default app for sms.

And now I have got notification that messages has got better. It detected Jazz sim as default from sim 1.

Don't know how it works and what are its features.

in this app if you try to video call you need to install another app and for voice call you are using standard sim network. Never gonna work against whatsapp failure from start

Well this explains the speeds I get on Jazz sometimes.

They're using 256 QAM modulation for LTE.

After some googling, I saw that 256 QAM requires a SINR of at least 17 dB to kick in, which is why it kept dropping back down to 64 QAM.

Despite only staying on for a few seconds, the speeds would burst from 50 Mbps, up to 80-90 Mbps.

Couldn't even take a screenshot since it would go away so quickly so I had to film the screen and then pause the video at the right time.

Well this explains the speeds I get on Jazz sometimes.

They're using 256 QAM modulation for LTE.

After some googling, I saw that 256 QAM requires a SINR of at least 17 dB to kick in, which is why it kept dropping back down to 64 QAM.

Despite only staying on for a few seconds, the speeds would burst from 50 Mbps, up to 80-90 Mbps.

Couldn't even take a screenshot since it would go away so quickly so I had to film the screen and then pause the video at the right time.

I wonder what the corresponding RSRQ value would be (as a general guideline) for a good SINR.

I wish I was rooted - but too many SafetyNet checks in place and all is a hassle. And I wish the app allowed us to grant it permissions via adb.

I thought it was a hassle too, but I'm actually enjoying having root again.

Not passing SafetyNet isn't bothering me very much since I don't rely on DRM for Netflix, Google Pay or any other apps that require CTS to pass.

I've hidden root from Jazz World since that crashes immediately if you launch it while rooted, and other than that everything else works just fine.

Ironically my Samsung galaxy A50 does not support CA for which Samsung charges whopping 50K. I will never buy a samsung phone again. Samsung is looting Pakistani People. For Galaxy S20 Ultra they are charging same amount which they are charging internationally but Pakistani variants does not support 5G.

yes it is true. No official store for flash memory, ssds and memory cards and usb sticks. I dont know why big companies dont have official stores in Pakistan.
