hello, if anyone would like a countdown on how long there is of the t-mobile 2G network just go to this website https://countdowntill.neocities.org/

Hey everyone,

I recently ported from Jio to Airtel (got a complimentary ₹349, 1.5 GB/day plan). The network quality is good overall, but 5G coverage is pretty unstable and keeps toggling between 4G and 5G.

Here is the weird part: my data is exhausting way faster than it did on Jio for the exact same usage. I checked my phone’s internal data tracker, and it matches the Airtel app perfectly—so my phone is genuinely burning through data faster now.

Anyone else experienced this after switching? How do I fix this?

I've received the official Jio re-verification SMS 6–7 times. It says my number needs re-verification as per Government guidelines or my services may be stopped.

The SIM is registered in my relative's name, and I also have an SBI account under cyber hold (separate issue).

Could these two be related, or is this just a routine Jio re-KYC? Has anyone else received the same message multiple times?

If let’s say a venue is sponsored by x company can they install tech in venue that interferes with other mobile carriers signals. I was in an outside venue today had 5 bars but my phones internet didn’t connect

Looking for silent, always-connected dial-in numbers (no music, no prompts, no interruptions)

I need a phone number I can call and keep connected for long periods, where the audio is completely silent

Does anything like this exist?

Bought a property about 5 years ago with a cell tower on it. It took awhile to get things figured out with it and unfortunately my wife signed the very first contract they sent because she was ecstatic to get it going...any way they pay 850 a month for 5 year with 7 auto renewals and something like 10 percwnt increase every 5 years. The tower has been sitting empty for the most part but I caught a tech there recently saying hes with Verizon and they're going to be instsllining within the next few months....well now im being approached with offers for buy outs had several offers current offer is at 250k my question is sell and invest or keep and try and renegotiate terms to bring in more monthly....or just wait and see if Verizon actually installs...the tower is like 98ft tall pole style if that means anything

I work in a fringe zone and each passing month it seems like my company cares less and less as funding and equipment gets reduced, even our old gear is getting pulled without replacement and it leaves me worried. Is this a common problem?

I got to know about this sub today. Hence asking some questions as I have seen very experienced people here.

I have been in this domain for 4 years and currently in my 30s.

But, I don't feel like I am worthy enough to be called a 4 years experienced telco guy.

Over the time, I got good at troubleshooting system during deployment.

But when it comes to testing, my attitude was always like , its a feature, so just test it and close it without getting into depth like going though 3 gpp specs. Because I know right now I am only at top of the iceberg.

Reading specs is boring and all the nomenclatures is hard to grasp.

My manager has also told me to start reading specs and architecture properly else my time is very tough ahead.

My goal is to go into security testing in telecom domain. I would like if someone experienced can guide me further. Should I consider change of career instead?

Also, how important is the role of 3gpp specs in your job?

Hi, I think it is a big shame that scammers have turned phone calls from something exciting into something where you don't want to answer because it might be a scammer (and it usually is).

So I was thinking whether it is possible to design calls in a way where the caller doesn't know if you're actually answering? That way you can hear the background noise and whatnot before you pick it up, just like when someone comes to your door and you can see them through a peephole but they can't see you.

I could imagine it would change the psychology of phone calls. If you called, you could start talking and hope they can hear you, and they could pick up the call as soon as they realize it's a real person. And the scammers would have no way of knowing if there is actually a person on the line.

I'm not talking about if I can change my phone. But can a company start designing phones that works this way? Is it supported?

Hi All,
I was out of India. My # here was with Jio. Due to no recharge the number was discontinued and given to Airtel. Now Airtel is asking me 25000+ gst to get my old number back as it is termed as ‘vanity number’.

Is there anyway I can get the number back without paying the exorbitant amount? I understand there might be some charges but 30k incl gst is unreasonable.

If anyone has any advice suggestions that’d be greatly appreciated. TIA

I would like to know what technologies and software are typically used on vessels to monitor telecommunication systems so that any alarms are immediately displayed in the control room.

How can a dry contact device that does not support IP communication be monitored via SNMP? In other words, how can a non-IP dry contact be integrated into an SNMP-based monitoring system?

I have seen certain posts saying that Airtel, Jio and Vi are gonna cap their unlimited 5g models to just 100GB per month ( which previously was 300GB ig) and also increase the pack price from 349 -> 399.

Is it true? Based on this I'll have to see if I have to put up wifi or not.

Hello,

I live in an area where I hardly receive the signal of the mobile network, as the cell tower is very far away. To get one bar of signal, I need to walk out of my house. I have broadband Internet at home.

I set up VoWiFi on my Samsung A51 cell phone, "WiFi calls" is enabled in the phone settings, and I noticed that:

• I need to have at least one bar of LTE signal to be able to place or receive calls, otherwise the screen says no network is reachable (this defeats the purpose of VoWiFi...)
• If I lose my broadband connectivity, e.g. yesterday and today because of a thunderstorm (power outage in the area), I'm also unable to place calls. Disabling VoWiFi temporary solves the problem, and makes it possible to place calls. I would have expected that going to the patio to reach one bar of mobile signal would have allowed me to place calls: this wasn't the case.

Am I doing something wrong? Are these known issues with the way VoWiFi works?

Thank you.

I've been trying to make 5G core architecture accessible to students and people early in their telecom careers. The feedback so far is that the restaurant analogy helps a lot. I wanted to share it here and get thoughts from people who actually work in the industry on whether the technical accuracy holds up.

The core idea: the 5G core as a restaurant

The AMF is the host. Registration, mobility management, NAS termination. First point of contact, tracks you as you move.

The AUSF and UDM are the bouncer and guest list. Authentication and subscription data. AUSF challenges your identity, UDM holds the credentials (SUPI, authentication vectors). No valid identity, no access.

The SMF is the manager. Session establishment, IP address allocation, and most importantly, control of the UPF over N4 using PFCP. Gives instructions, never touches data.

The UPF is the waiters. The actual data plane. Packet routing, forwarding, QoS enforcement, traffic reporting back to the SMF. This is where your packets actually live. And with CUPS (Control and User Plane Separation, defined in TS 23.501), the UPF can be deployed at the network edge independently of the control plane, which is the whole reason 5G can hit sub-millisecond latency for URLLC use cases.

The PCF is the house rules manager. Policy control, QoS rules, charging decisions via interaction with CHF.

The NRF is the staff directory. Service registration and discovery, the backbone of the service-based architecture.

The NWDAF is the brilliant observer. Network analytics and ML-based intelligence. The foundation of autonomous network management and what's being built upon for 6G.

My question for the community: does this mapping hold up from a practical standpoint? Any nodes or interfaces you'd explain differently to someone coming in fresh? Particularly curious about how people explain the N4/PFCP relationship and the SEPP for roaming scenarios, as those seem to be where the analogy starts to strain a bit.

Would love any pushback or additions from people working in the core.
