A Uruguay eSIM dual SIM setup lets the travel profile provide mobile data while the home line remains available for its number, subject to the phone and home operator. The essential control is choosing the Uruguay eSIM for data and preventing the handset from switching back automatically.
Keeping a home SIM active can still create charges for incoming or outgoing calls, voicemail, SMS or other roaming services under the home operator’s terms. A travel eSIM does not change those terms, so check them before departure.
NoveSIM Uruguay plans are data-only and do not provide a local number, traditional calls or SMS. Apps such as messaging and internet calling can use the travel data, while the home number remains associated with the home SIM.
Quick answer: Label the lines clearly, choose the Uruguay eSIM for Mobile Data, enable roaming only on that travel line, disable automatic data switching and keep home-line roaming off. Leave the home line active only if you need its number and understand its operator’s charges.

How a Uruguay eSIM Dual SIM Setup Divides the Jobs
| Task | Line to use |
|---|---|
| Mobile data in Uruguay | NoveSIM Uruguay eSIM |
| Home telephone number | Home SIM, if kept active |
| App messages and internet calls | Travel eSIM data |
| Traditional calls or SMS | Home SIM under its roaming terms, or another service |
| Local Uruguayan number | Not included with a data-only NoveSIM plan |
Review the current travel plan on the Uruguay eSIM page and confirm the exact handset on the compatible-device list. Dual-SIM and simultaneous-active-line capabilities vary by model, regional version and software.
Label Both Lines Before Travel
Names such as “Home” and “Uruguay Data” make settings easier to verify at a glance. Do this immediately after installation, while reliable Wi-Fi and the order details are available. The Uruguay eSIM installation guide covers the profile-installation stage separately.
Do not remove the home SIM merely to simplify the screen if you need its number for account messages. Instead, decide which services can remain enabled and document the home operator’s roaming charges.
Recommended Dual-SIM Settings in Uruguay
| Setting | Recommended choice |
|---|---|
| Mobile Data | Uruguay Data eSIM |
| Travel eSIM Data Roaming | On |
| Home SIM Data Roaming | Off |
| Automatic data switching | Off |
| Default voice line | Choose deliberately according to your calling plan |
| Network selection | Automatic initially |
The travel line may require Data Roaming because it connects through partner networks. That does not mean roaming should be enabled on the home line. The two toggles are independent.
Keep the Home Number Without Using Home Data
- Leave the home SIM switched on if the number is needed.
- Turn its Data Roaming off.
- Select the Uruguay eSIM as the sole Mobile Data line.
- Disable automatic mobile-data switching.
- Use app-based calling and messaging over the travel data where practical.
- Review the phone’s indicators before placing a traditional call or sending an SMS.
The guide to keeping your main number with a data-only eSIM explains the general arrangement. Availability of Wi-Fi calling and how a home operator bills it are operator- and device-specific, so do not assume it will be free abroad.
Avoid Accidental Data Roaming
Some phones offer “Allow Cellular Data Switching”, “Switch Mobile Data Automatically” or a similar control. Turn it off. Otherwise, the handset may use the home SIM when the Uruguay connection weakens, even though you intended the eSIM to handle all data.
Check the status after restarting the phone, leaving Airplane Mode or crossing a border. A country-specific Uruguay plan should not be assumed to cover Argentina, Brazil or an international ferry crossing.
What Happens to Calls, SMS and App Messages?
Traditional calls and SMS stay associated with the line that owns the telephone number. Receiving them abroad may be chargeable under the home operator’s policy. NoveSIM data does not convert them into free services.
App messages usually continue on the account already registered in the app, even though the internet path changes to the travel eSIM. Avoid signing out or re-registering an app unnecessarily simply because the data line changed.
Fix the Wrong Line Using Data
- Turn Wi-Fi off and open the Mobile Data settings.
- Select the Uruguay eSIM explicitly.
- Confirm its Data Roaming is on.
- Turn automatic data switching off.
- Confirm home-line Data Roaming is off.
- Toggle Airplane Mode for about 30 seconds and test a fresh webpage.
If signal appears but data still fails, check the allowance and enter data.esim only when manual APN configuration is required. Follow the Uruguay eSIM troubleshooting guide and do not delete the installed profile unless NoveSIM Support explicitly instructs you to do so.

FAQ
Can I keep my regular number while using a Uruguay eSIM?
Often yes on a dual-SIM-capable phone. Keep the home SIM active for its number, but select the Uruguay eSIM for data and check the home operator’s roaming charges.
Should roaming be on for both lines?
No. Enable Data Roaming on the travel eSIM when required and keep it off on the home SIM to reduce accidental home-line data charges.
Will WhatsApp keep my existing number?
Usually the app account remains registered to its existing number while using travel data. Do not re-register it simply because the phone’s data line changed.
What APN should the Uruguay travel line use?
Use data.esim only if the NoveSIM profile requires manual APN entry. Keep the eSIM installed during troubleshooting.
Final Recommendation
For a Uruguay eSIM dual SIM setup, label both lines before departure and decide exactly which services the home SIM must retain. Check its operator’s roaming rules separately.
In Uruguay, assign mobile data to the travel eSIM, enable roaming only on that line and disable automatic switching. Use data.esim only when manual APN setup is required.
Keep the installed profiles and verify line selection after restarts or border crossings. Clear labels and deliberate settings allow the home number to remain available without silently turning it into the data connection.
