1 · The short answer
A digital nomad needs one phone number that stays reachable in every country, and today no single cheap setup gives you that together with data. The setup I recommend for now is your home line kept switched on for calls and bank codes, with a travel eSIM beside it for data.
That is two plans doing the work of one. A single plan with your own number that works in every country is what the full Ringo service is being built to be. It is not on sale yet. I write for Ringo, so weigh that, and read the rest as a comparison of what exists today.
The waitlist is free and it is the way to hear when it opens.
2 · What a phone has to do when you move every few weeks
A two-week holiday forgives a lot. Someone who changes country every few weeks has no home base to sort things out in, so I would hold the phone to three tests:
- Data everywhere. Maps, work calls, the laptop on a hotspot.
- One number that clients and banks can reach. The number on your invoices, your bank file and your email recovery should be the same one in month one and month ten.
- Bank and login codes arriving. Banks send transaction codes by text. Work systems, brokerages and government portals use the number as a second factor. WhatsApp and Signal re-verify with a text to it.
The first test is the easy one now. The second and third are where the setups below differ. A number that lapses can be recycled and handed to a stranger, and then every service you signed up with has to be recovered one by one.
3 · Setup one: home plan plus a travel eSIM for data
This is the setup I recommend today. Your own SIM stays in the phone with data roaming off. A data-only travel eSIM sits beside it and carries everything that needs the internet.
It passes the number test because texts travel over the network signal and not over data. As long as your own line is switched on and registered on a local partner network, a code sent to your number arrives. WhatsApp stays tied to your number and runs on the eSIM's data. I set out the menus in the .
The weak point is that you pay for two things, and the home line was not designed for a life abroad.
- The home plan bills every month, mostly so that a number can receive codes.
- Receiving a call abroad is often not free. Outside a roaming bundle, many carriers charge by the minute to take a call, and some switch on a daily roaming pass the first time the line is used.
- Some prepaid and budget plans block roaming unless you switch it on in your account. With roaming barred, the line shows No Service and no texts arrive.
- Some banks refuse to send codes to a number while it is roaming in certain countries. It is rare, and no phone setting fixes it.
It works. I would still call it a workaround.
4 · Setup two: a new local SIM in each country
The classic answer: land, find a shop, buy a local SIM. You get local data and a local number.
The weak point is that the number changes with every border. Clients cannot keep up with a new number every few weeks. Your bank still sends codes to the old one. So the home line has to stay alive anyway, which brings back the home plan bill from setup one.
There is also a trap. If you take your own SIM out to make room, codes stop arriving. And if you cancel the home plan to save money, the number goes back into the pool.
5 · Setup three: an internet calling number
The third route is a number from an internet calling service. It rings in an app, over whatever data you have, so the country you are in stops mattering. Add a travel eSIM for the data and you are set up.
The weak point is that it is a second number, not the one the world already has for you. Your bank, your clients and your accounts all hold your existing mobile number. You would have to change it one service at a time, and each service decides whether it accepts the new number for codes. I would ask your bank first.
It also only rings while the app has data.
6 · The three setups side by side

I have left figures out on purpose. Every carrier prices roaming differently, and your own carrier's roaming page is the honest source for yours.
7 · What one plan with your own number would change
Every setup in the table splits the job in two: one product for data, another for the number. The costs and the failures sit in the gap between them.
A single plan that works in every country, with your own number on it, would close that gap. The number your bank and clients already have, moved across by porting, which is a standard process and a legal right in most countries. No home plan kept alive only for codes, and no new number at each border.
That is what the full Ringo service is being built to be: one plan that works everywhere, with your own number included. It is a separate product from Ringo Light. It is still being built, and it is not on sale yet. I have no date and no price to give you, and I will not guess.
The free waitlist is how you hear when it opens. Until then, I would keep your home number active, because a port needs the number to be live with your current carrier.
8 · What works today for the data half
For the data half of setup one, I would look at Ringo Light Global. It is the one Ringo Light plan that renews monthly, and it covers 133 countries, so the same eSIM stays installed as you move. It is data only and sits beside your own SIM, which keeps your number working for calls, texts and bank codes on the home line. Data is unlimited at full speed. Fair use policy, see Terms. It arrives by email with a QR code after payment.
You can see it in the , next to the trip plans for single countries and regions, which are paid once and do not renew. A data eSIM is not the full service and gives you no place on it. The explains what a data-only eSIM can and cannot do for your number.
