If you are travelling a lot to different countries, you have probably had problems handling multiple phone numbers, data plans, and 2FA codes. Below are best practices that work well for digital nomads and long-term travelers when it comes to phones, phone numbers, international data, and 2FA codes while abroad.
How to Handle Different Phone Numbers and Data Plans
Main Phone Setup
Your main phone should be:
- network unlocked (not restricted to one carrier)
- eSIM-compatible or at least dual-SIM compatible (Google Pixel is a solid option)
- protected with a case and screen protector
Backup Phone
You should also have a network unlocked, inexpensive backup phone. Ideally it is dual-SIM or eSIM-compatible, but this is not a deal-breaker.
Keep this phone in your luggage at your apartment or accommodation. Use it only if your main phone gets stolen, broken, or lost.
Home Phone Number and VoIP
If your home country phone number is not an eSIM, transfer it to a free or inexpensive VoIP service and ditch the physical SIM card.
- Americans: Google Voice
- Canadians: Fongo
Even if your number is already an eSIM, switching to a VoIP service still makes sense since it is usually free. There is no reason to pay for a service you do not need.
If you are neither American nor Canadian, search for VoIP phone number apps for your country or use a US or Canadian number specifically for 2FA.
If you do not want to give up your physical SIM, keep it stored safely in your backup phone while abroad.
Handling 2FA Codes While Abroad
Use Authenticator Apps When Possible
If any of your accounts allow authenticator apps like Authy or Google Authenticator instead of SMS-based 2FA, switch to them.
Use VoIP for SMS-Based 2FA
For accounts that do not support authenticator apps, use your VoIP number for receiving 2FA codes.
In some cases, SMS messages may not arrive to VoIP numbers. This is the main drawback, although it is becoming less common over time.
Fallback Options for 2FA
If VoIP does not work for certain accounts:
- ask a non-nomadic relative if you can use their number
- have them send you the codes via WhatsApp when needed
If this is not possible, get a cheap SIM card from your home country that supports receiving SMS on a basic talk and text plan. These usually cost $5 to $10 per month. Keep this SIM in your backup phone.
Prepare Your Backup Phone
Your backup phone should have all important apps installed, especially your VoIP app, and everything should already be logged in and set up. This allows you to instantly access your accounts if your main phone becomes unusable.
Consider switching your WhatsApp number to a VoIP number so you can easily recover your account if you lose your physical SIM.
Internet Access While Traveling
For mobile data abroad:
- use local prepaid SIM cards

If you need to call or text back home, your VoIP number usually allows this for free or for a small fee. If you need to contact local numbers and your data plan does not support calls or SMS, VoIP apps usually work for that as well.
Whenever possible, rely on apps like WhatsApp, Facebook Messenger, Telegram/Signal or Instagram instead.
Additional Unrelated Tips
Money and Cards
Travel with:
- a backup debit card
- a backup credit card
- emergency cash (around $200)
Store these separately in your luggage at your accommodation. Keeping some money in PayPal adds another safety layer. If your banking app allows card locking, use it.
Use debit and credit cards with no foreign transaction fees, conversion fees, or ATM withdrawal fees. Ideally, use a debit card that refunds third-party ATM fees, such as Charles Schwab for Americans.
Cash Withdrawals
Do not exchange cash at currency exchange offices. Withdraw cash from ATMs instead.
Always decline the ATM’s conversion and let your bank handle it. Use ATMs inside banks when possible. Hide your PIN and tug lightly on the card slot to check for skimmers.
Power and Accessories
Bring:
- a power bank (10000 mAh or more)
- spare charging cables and wall chargers
- at least one extra cable and charger in your luggage
A longer cable (around six feet) is useful in accommodations with poorly placed outlets. Fast charging support is recommended.
Other Useful Items
Also consider:
- an extension cord or plug adapter
- a small lock for hostels
- earplugs
- digital copies of important documents stored in the cloud
Keep your physical passport secured at your accommodation and avoid carrying it while sightseeing.
