@@discostu333 glad this was helpful.

And thanks for taking the time to watch it :)

Glad to hear that

Thank you for your kind words:)

@@angieng71 That is a GREAT question. In short, yes you will be able to receive and make calls on VoLTE even if mobile data and WiFi are off. That’s because the signalling continues for voice & text which are also transmitted/received on packet switched technology BUT in a more dedicated way so not using mobile data like the Internet does. For VOLTE there are very strict service quality requirements so mobile networks make sure to deliver it as a higher priority to ensure that quality level. It uses the IMS platform for voice calls and SMS which makes this happen.

Oh I wish that was possible. I know what you mean, it would be great to be able to slow some people down. If you really need to specifically deal with one particular message, you could upload that message as an audio file somewhere to listen at a slow rate. KZbin has that feature so if you upload that audio as a private KZbin video (so that it’s only available to you :)), you can play that at 0.5.

5G New Radio is the name of the technology so overall 5G technology including the full network (of course appreciating the intricacies around standalone and non standalone). NG- RAN is just the 5G radio network specifically. Check out the 5G overview part 2 (I think) which dives into the architecture. That’ll highlight the overall 5G NR as well as the 5G radio and core networks.

You’re making a good point. In fact, 3G was providing a decent fallback option for 4G and 5G. But given the data speeds of 4G & 5G and the move to IP based voice, 3G isn’t adding a lot of unique value, just a back up. Same for 2G also, but 2G still provides IoT services like smart meters etc. The beauty of 5G networks is that they can work with all kinds of frequencies, low, mid and high so they can technically replace all earlier technologies when they are mature. So that’s why the gradual phasing out of earlier networks like 2G and 3G makes sense so that these resources can be used for the future 5G networks.

@@ZardoshtHodaie Thank you

@@shaunigothictv1003 Sorry to hear that. While HSPA is technically capable, the performance depends on how many people are being simultaneously served by the same channels that are serving you. So it all boils down to the utilisation of the available capacity (bandwidth). In real life deployments today, anything 3G is unlikely to give you a decent internet connection. But still better than 2G of course. 4G and 5G are in a different league compared to 3G. So with 3G, it’s not your phone, it’s the network that is slowing you down because the output of your phone is limited by the input it receives from the network.

@@CommsbriefLimitedOfficial Ok thanks.

@@Lexyvil I’m glad you hear that the video helped. Thank you.

just move on

@@KrsJin Glad to hear

Hello, thank you. It’s in the description and also here: commsbrief.com/5g-new-radio-what-is-5g-nr-technology-and-how-does-it-work/

It’s illegal for any individuals to change the IMEI number in many countries including US, UK, Canada, Germany, France, Australia, India, Pakistan, South Africa and many others. It’s managed very strictly because it’s a very sensitive number. Only authorised personnel are able to track you. The exception is, of course, some countries where corrupt elements have access to this database. Now to address the problem you’re trying to solve: If you have a dual SIM phone, which is highly possible nowadays with eSIM, just use a different SIM compartment. Or change your phone.

@@frankryan782 Easy way to know: If there is a SIM, there is an IMEI. No SIM, no IMEI. If WiFi only and no SIM, then no IMEI.

Well many KZbin videos saying that even using WiFi only without sim your device will transmit it's imei number. . Are you saying a WiFi only device cannot transmit it's imei number to the network it's using ?

@@frankryan782 An IMEI number is only transmitted when a cell phone connects or tries to connect to a mobile cellular network base station. That happens when a SIM card is inserted OR a phone with no SIM makes a call to emergency numbers like 911, 112, 999 etc. OR a phone with no SIM tries to search for a cellular network. The third one is very very unlikely and therefore if you have a phone with no SIM but a Wi Fi connection, it will only transmit IMEI if someone dials emergency numbers. In the UK for example, that means 999 and 112, and in the US, that means 911 and 112. So if you were to look for a general scenario (when you’re hopefully not dialling emergency numbers), the likelihood of IMEI being transmitted without a SIM would be close to negligible.

@@frankryan782 Yes. The the IMEI belongs to the SIM card slot in your phone even if it’s eSIM because the slot for that is inside your phone. The only thing SIM does is to establish the connection between the phone to the network using the SIM slot IMEI number. So as long as the phone is talking to the mobile network (using SIM), the same IMEI is communicated.
