Every time I buy something online, or make an account for an example month bus ticket, they “need” my phone number. I always use alias emails, but I don’t have an alias phone number. I know, there are some online phone nr service, but they mostly dosnt work, outside of the US. So I was thinking about getting me a second nr, just for thoese cases were I have to log in. I would by the nr, in cash, and there is nothing data they have to make the nr. But what are your thoughts? What do you see as pros and cons for getting a second nr.? Does it even make sense, when the simcard is in the same phone?
Pro: the second line can be deactivated (“disconnected”) from the phone. Con: added cost.
So yir its not that bad a idea. 😀 the Sim carrier is a one pay thing, so if I want to call from it or so, I have to put money on it.
You don’t have to get a mobile number. You can get a number from a voip provider. Those numbers can accept sms usually. Usually cheaper than mobile number and you can access from your phone with a SIP client.
Okay, i will look into that. Thank you
Depends on your local laws and such, but in most European countries you can get a prepaid SIM card for a couple of euros/pounds/whatever at any supermarket, making them practically free. If you need a temporary number for a scammy special offer or any situation where your number is publicly visible (Gumtree, etc) it’s a no-brainer IMHO.
If your phone suppprts running two SIMs at once, it has two IMEIs so as far as the network(s) are concerned it’s two distinct handsets unless they deduce otherwise.
A fun aside: years ago I did some work for a small phone company (the company was small, not the phone) and they gave me a SIM with 100 numbers in a block and access to a portal I could manage them with. Sadly, I forgot to pay the annual £10 renewal fee.
I got a second number for a while and saw no real benefits and went back to one
I have been doing precisely that. You have your personal number and the secondary number that doesn’t have to be attached to your name if you want. Ofc law enforcement and telecom companies will be able to trace you based on cell tower locations and phone model.
Pro: An extra disposable number to give out whenever people ask you for “we need your phone number for ShittyDiscount”. Whenever the spam calls get annoying I simply pop it out and place another prepaid sim.
Con: Phones with dual sim support can be rarer to find and be more expensive depending on your country.
Iirc all modern iPhones have two sims - one eSIM and one physical.
Getting another number helps a lot in my opinion. If you’re getting another sim in the same phone, I suppose it would be possible for whatever cell carrier is providing the service to be able to link your two sim cards to your identity. However, for other companies, I don’t know of a way they could gather that your second sim phone number is linked to your first one. For instance, if you created two Discord accounts with your two phone numbers, you could theoretically be two completely different users that won’t be linked together. I would personally go for a second number.
Best way to combat the issue in this example is to create zero Discord accounts & embrace open, encrypted communication options like XMPP & Mumble, etc.
Yir that makes sense. It helps to hear from others, because my brain is getting so confused by over thinking the “problem” thank you for the answer.
During covid, i made a Google voice number so i didn’t have to give my real number when we were working from home. It was fine for that.
A surprising amount of services block Google Voice for 2FA (where a surprising number of services both required 2FA & only support SMS despite the security issue); I wouldn’t rely on it (but sometimes it still makes the most sense since you can’t beat the price, free). My favorite was PayPal deciding to block Google Voice & the only way to message support is by first authenticating—where asking on Twitter was an immediate block so… fuck PayPal & never used it since.
This is a good question. Phone numbers are increasingly used as de-facto ID numbers, everywhere in the world. That’s because, unlike email, they cost money, and in most jurisdictions you can’t even get one anymore without presenting real ID. So: if you have a second phone number, you can effectively have a second persona for any site or app that requires phone-number ID. Seriously, at this rate, it’s going to be all of them.
IMO the best use-case for this is to quarantine your contact list. That is, keep a separate number for social networks and messaging. The number you give to your in-person contacts will be instantly shared with all their cloud services, whether you like it or not. This is what allows Big Tech to triangulate and discover exactly who you know and therefore who you are. If the cloud services cannot trace a number back to any phone ID in their own books, then they can’t do much with it and you will remain at least something of a mystery to them.
Thank you. Well its gonna be a lot of work, to get all the contacts my new number, but yir just to get a little bit of privacy I think its worth it.
It really helps my confused brain to hear all your ideas and suggestions! For me it seems there are more pros than cons, so I will go to the local store and buy a prepaid Sim 🙂
ESIM using silent.link = a phone line that can only be used to receive messages and calls no outbound calls allowed. However you need a phone with esim support.
Physical sim on another device: great but you need a seperate hardware and have something extra to carry and charge.
Physical sim on a dual sim phone. Easier to carry however it runs the battery faster and sometimes you can forget which sim you are on if you are quickly calling or texting.
Mains sim plus VoIP line example is mysudo- use one phone, seperate your communication between your actual number and an app with VoIP. Seperate phones # via software since VoIP is all on app side. Requires you have an internet connection to work properly. Not all services are happy using VoIP and stop you from registering or changing numbers to VoIP.
Lots to think about, best of luck.
Thank you. 🙂
