Urgent Help Needed : Airtel Re-verifcation Issue

Hi all,

I’m facing a serious issue with my Airtel number, and I’m running out of options. Here's the situation:

I’ve been using my Airtel SIM for the past 10 years. When it was registered, I was 14 years old, so my brother used his documents to get the SIM for me. Now I’ve received a message from Airtel saying I need to complete the reverification by December 5th, or my outgoing services will be restricted.

I went to the Airtel store, and they informed me that since the SIM is in my brother’s name, he has to be present for the reverification. However, my brother is currently in Canada and won’t be coming to India anytime soon.

I then tried porting the number to another service provider, but the request failed with the message:
"UPC cannot be generated as there is an active request for the change of ownership for this number."

When I asked the store executive, they said the reverification needs to be completed first—but that’s just not possible because my brother isn’t here.

I have only a few days left before the services are restricted. Has anyone faced a similar issue? Is there any way to resolve this without my brother being physically present? Any advice would be greatly appreciated.

Thanks in advance!

Do you know how to get the phone number of no-reply SMS?

I received some verification codes or banking SMS, but these SMS only showing are sent from a brand name, can't see their phone number, and almost them are no-reply SMS. I want to know the phone numbers behind the brand names, do you know how to get them?

Bank won't send me a one-time password. They say my phone is not eligible. Why might that be? What do they know about my phone? And how can I fix it?

I am having problems using my phone to conduct banking business. My bank has been supremely unhelpful. I'm wondering if someone who works in the telecom field might be able to offer some insight.

I am trying to transfer some money either using Zelle or a wire transfer. My bank will not let me do either through their web site. Through many frustrating phone calls with my bank's customer service line, I have learned that my phone is not eligible for receiving one-time passwords to confirm fund transfers. (Although my bank will send me text messages for other reasons.) The customer service representatives could not tell me why my phone was ineligible and they could not make it eligible. They have no technical escalation procedure. Their only solution was to allow me to lodge a complaint. Eventually someone responded to my complaint to tell me that my phone is not eligible to receive a one-time password.

A different financial institution, which I use for investing, at first had similar trouble with two-factor authentication. But a call to that bank's support line resulted in me installing an authenticator on my phone, and I was able to complete my business with this other bank's web site.

The only unusual thing about my phone is this: I recently moved to the US and immediately bought a prepaid SIM. After a couple weeks, I transferred the prepaid SIM's phone number onto a new phone, which I received with a regular service contract.

So my questions are these: Why might my phone not be eligible for receiving one-time passwords? Why won't my bank tell me what the problem is? Is it because my phone number started as prepaid? Is it because I changed my phone number to a different carrier? If that's the case, how does my bank even know that about my phone? And will my phone eventually become eligible? What can I do to make my bank use my phone for one-time passwords?

BEAD Lead Times

Does the industry expect telecom suppliers to run into lead time issues once BEAD projects start in earnest? I can remember 20-week lead times. I remember as recent as two years ago coming out of COVID, lead times for fiber at 50 weeks, HDPE Conduit at 15-20 Weeks.

Has the industry built up enough capacity to meet the demands of BEAD?

Why is 5G with one bar much slower than LTE with even 2 or 3 bars?

T-Mobile service Google Pixel 7 says 5G but can't even run GPS service. Makes me wonder sometimes if 5G really is 5G with done providers

Satphones and when is a call long distance

Hi everyone

TLDR: Should I pay extra monthlt fee for my Iridium satphone to have a +1 number instead of and 8816 number? When using a normal conventional phone calling a normal conventional phone, like two American phones calling each other, what happens when travelling abroad in terms of international calls? For example, when I'm traveling with my iPhone in Angola, and my neighbor back home decides to use his iPhone to call me, does he pay international? Will it warn him?

These are some very niche questions. I hope this is on-topic, there appears to be no community for phones in general and these questions did not seem appropriate for r/apple or r/androidphones.

Just to be clear I'm an American and live and spend most of my time in USA. So I am going to be purchasing an Iridium satphone soon (hopefully find a good one used) I have to pay at least 65$/month. I have to decide if I want to pay an additional 7.50$/month to have a +1 US number instead of Itidiums +8816 number (as far as phones are considered, Iridium has their own "country"). Is this true to begin with? I've seen varying prices for the US phone number for Iridium online and one guy in another reddit community told me he doesn't have to pay for his US phone number, its included.

Say I decide to slave it in the trenches with the 8816 to save money. If I call a +1 number (normal conventional American landlines and/or cellular telephones or other satphones)

Am I paying the long distance rate? Or is Iridium covering this? How does that work?

Obviously a huge advantage of paying extra to have a +1 is that when my mom or Billy bob or my boss calls me with his conventional landline or cellular telephone, it's just like a normal call and he doesn't get charged any differently than normal. Correct?

So I think I understand that paying extra for a +1 a huge advantage for whoever is calling me, I just cant figure out if it matters when I'm the caller instead of rhe recipient. If it doesn't matter when I'm the sender instead of the reciever, I may slum it out to save the 7 bucks. And just tell me friends to not call me unless it's an emergency and to have me call them instead.

Also, I have a question that has nothing to do with satphones. If me and my next door neighbor who both have iPhone call each other frequently, and I go on a work trip to a foreign country, and my neighbor calls me, because I'm roaming in a foreign country, does he pay international fees even though my number is and always has been a +1? This might depend on my situation. I know with AT&T now i pay like an extra 10 bucks in a month if I roam in almost every country and other than that it behaves like normal so maybe in that situation if my neighbor Bob calls me he doesn't have a problem? Are there ever any situations where you call call a +1 number that's outside the country, and because of that you even though you are within the us you get charged because the American recipient just happens to be travelling internationally? In that situation, would a robot say "FYI, if you proceed, you're about to incur charges because the recipient is travelljng internationally".

Or rather, does do a call collect for the recipient?

Thanks so much!!!!

tdr on single conductor possible?

my purpose would be to find distance to open on a trace wire or even the metal sheath on a fiber optic cable (locating underground)

more of a fiber guy, but back in the day i remember running multimeter tests on twisted pair and i needed tip,ring, and ground.

well ground is no problem, and i have 1 conductor id like to test the distance of.

would red lead to my conductor, and black lead to ground give me an accurate distance to open reading? do i need a 3rd lead?

basically i’m trying to find out if the other end of my conductor (500 ft- 1mile away) is bonded to a ground (it should be)

and if not, a distance to open would tell me where its not grounded at pretty much.

Fair price for cell tower land lease in a Canadian Prairie city?

My parents own 2 acres of land in an area that is coming up for development in Winnipeg, Manitoba, Canada. We expect the major developers to want to purchase their land within 10 years.

They have now been contacted about a cell tower lease. The company is called "sharetower". I am sure all the property owners in the area have also been contacted. I need to know if this is something actually reasonable:

  • 10 year agreement with an additional 10 year automatic renewal (effectively making it a 20 year deal).

  • $1,000.00 per month in rent.

  • 20% rent increase every 10 years.

  • There is at least a 1 million dollar insurance policy on every tower we build.

  • Rent payment/lease term hinges on construction. If we sign an agreement, there is no guarantee they can use the space for its intended purpose. I don't know where that leaves my parents.

This seems like a real lowball. It will certainly reduce the value of the rest of the land. However, if my parents pass, the tower will just go up a few hundred meters away. I personally think the rent should be double that and the increase structure should be every 5 years.

Thoughts? I need to look into this more. There are some other factors. There is no guarantee that developers will be ready to move in this area within 10 years. My parents aren't getting younger and this land has just been costing them taxes for the past 40 years.

Is the free telecoms skills course worth it?

Telecoms skills offer a level 3 BTEC in relation to telecoms. It's free and government funded but 8 weeks full time so would have to commit to not working for two months. I'm currently unemployed so is doable but will be difficult financially as I can't apply for other jobs if I commit to this.

Im sure it's not the most detailed course but I was seeing if worth it or if anyone else decided to do it? Thank you

Looking at Applying for OSP Engineer Position

I graduated with my Master's in Materials Engineering. I want to stay in my hometown but there's not many engineering jobs and waiting on responses from interviews. I have experience in laser and photonic systems which the course had a fiber optic section where students had the chance to strip, cleave, polish, terminate, and fusion splicing. The position is asking for a B.S. in engineering, experience in Microsoft Office Suite, and corporate data and reporting platforms (Excel, Tableau, Cheetah, or others). I feel I have everything covered. I also have experience in CAD/Inventor. I took engineering design and also was a mentor for the course. I look into OSP design and saw that GIS software is good to know as well. I know about it GIS from college but never tried to learn it. I also took course in E and M, electrodynamics where I learn about impedance matching and antennas. I am interested in this position. Thank you for your time and advice.

Jio sim down/no service/dead (temporarily)

For approximately 30 mins my sim went off, i tried switching devices. So i called the jio helpline from a different number, their IVR says, it’s a temporary glitch it will be resolved soon.

Meanwhile I thought I should visit the service center assuming that my sim is dead / rotten, and maybe the IVR is just another general message.

But now suddenly it has started working.

So putting this thread so no one gets panocked like I did.

Your sim will go from No service > service soon

PagePac 6 paging device question

Posting here hoping someone knows a little about this old device. I'm wondering if an Algo 8180, which has a 600 ohm output, would work with this for paging. For simplicity, I want to tie into the PagePac and use their existing network of paging horns. The company I work for does not install paging amplifiers, we just provide SIP endpoints, and if the Algo can interface with the PagePac, that would be good enough.

Telecom lineman pay

I am interviewing for a telecom job where they pay 8 cents a foot for linemen. I was told it’s 8 cents each for strand and fiber. I was wondering if that’s low or a decent rate. I’ve only ever worked an hourly job but im not opposed to working a production job I just want to make sure I’m not getting tricked.

SMS Firewall in 5G networks

I am creating a firewall to assess SMSs sent on a 5G network. I've got a few doubts on where to place it, here are my options:

  1. As a proxy between the AMF (Access and Mobility Management Function) and SMSF (SMS Function)
  2. Separate node connected to the SMSF. The SMSF would send the content and message information to the Firewall and receive an ACK or status update on the SMS.
  3. Between the AMF and UDM.

Any other suggestions are welcome!

For anyone curious, I am simulating the 5G network on OMNeT++, with INET and Sim5G.

Telecom engineering student laptop

I have decided to pursue this career next year, but before that, I would like to have my own laptop, as I have always had to borrow my dad’s. What laptop would you recommend for this engineering field? I’m looking for something lightweight, with good battery life and power. I was considering a MacBook since I’ve read that its chips are very good, but I’m open to other recommendations!

Suggestion for sim card y

Hey guys, I just ported to Airtel 3 months ago, postpaid was on now want to convert to prepaid. Can anyone suggest any better plan for Airtel, it could be quarterly or 6 months, I checked for yearly plans and I don't think they are that much of worth,

For background I already have primary jio number with yearly plan so this will be more like a backup So, want to pay as minimum as possible
