2 factor authentication all over the world?

I am Danish, with a temporary address in Spain - it will change to Colombia within the next year. I have a Danish phone number and so far I have managed to work with 2 factor authentification from my banks etc because I go to Denmark every 3 months.
However, I would love to not go back.
How can I get a reliable texting servie/platform that makes it possible for banks etc to send me codes for two factor authentification?

I looked at Plivo, but it makes no sense to me and looks like I have to code or something. I don’t want to change sim in every country, because for the next year I will be all over the globe.

What to do? I am sure it’s possible, but how?

Than k you very much :slight_smile:

I haven’t found a service that reliably works will all banks/services across the world. The problem is that many banks refuse to work with any virtual numbers, they require you to actually have a physical SIM card.

So the most reliable (and still relatively easy) solution is to get a cheap “dumb phone” where you put the SIM you use for 2FA and bring it with you wherever you go.

Just make sure that the phone supports phone networks across the world (look at quad band phones, they typically do) and just in case you need to pick up another SIM card to work with a specific bank/country later, I’d also recommend getting a dual sim phone.

The SIM card/subscription itself should support international roaming and be able to receive SMS for free—which is the case for most non-North American providers I’ve seen.

If it makes most sense for you to keep a Danish SIM card, you could move your number to Oister.dk—they have a plan where you only pay 19 DKK per month.

In other countries it might be easier to find pre-paid SIMs which can be topped up online every now or then to keep the number alive. This is often cheaper. For example, to keep my Norwegian number alive I only have to top up 25 NOK (~€2.5) every 15 months.

If you’d rather not bring an extra phone with you, you could use an Android smartphone instead (you can find these for pretty cheap) that you leave connected to WiFi at your home base (if you have one) or with friends or family. Then you install an app on the phone that will forward any SMS that you receive to your email.

There are also dual-SIM adaptors available (https://www.simore.com), but as Thomas says, a cheap mobile may be simpler.

Again you come up with a great idea. Thank you!!! I will leave a phone in Denmark and have it send texts to my email - brilliant. Thanks!

These look neat, @pbm. Thanks for sharing :slight_smile: Have you used them yourself? If so, what has your experience been like?

I haven’t used them, but their hands-on videos do a very good job of showing exactly how they work: https://www.youtube.com/watch?v=2g0pzgF3Rno

I wanted the bluetooth one, so that I wouldn’t have to use a case, but was put off by the price. There are other brands available on Amazon, but with similar prices.

Unless you leave it with someone,it will get switched off

You can get a sim from worldsim. It works everywhere you go. I have been using the UK one and it works wonders. You don’t ever have to pay for roaming or getting text messages worldwide.

For this purpose, I have used a US burner number from Hushed (app). It functions as a virtual mobile number whenever you have internet, and it is able to receive SMS from most institutions. Take a look at stacksocial, for sometimes they offer an everlasting US number voucher for only USD 25!

On the other hand, my UK virtual number with them is mostly useless.

Just a quick update. After much complaining to Hushed, they finally managed to make my UK mobile number with them. So that is finally settled.
