Optimizing dual eSIM functionality while traveling outside of the US (and saving money, hopefully)

Using dual eSIM with Google Voice while traveling outside of the US

Yes, you should be able to receive calls to your US mobile number from friends back in the US via GV on the

European data plan, even if the US eSIM is turned off. This is because GV is a VoIP service, which means that it uses the internet to make and receive calls, not your cellular network.

Using iMessage and FaceTime with a turned-off eSIM

As for iMessage and FaceTime, you will not be able to send or receive them from your US mobile number while the US eSIM is turned off. This is because iMessage and FaceTime require an active cellular connection.

Saving money on international roaming

If you are traveling for a few months, a European mobile plan will likely be cheaper than using international roaming on your US mobile plan. You can also consider using a prepaid SIM card from a local carrier in the country you are visiting.

Here is a summary of your options:

Option 1:

1. Forward your US mobile number to your Google Voice number before leaving the US.
2. Once you arrive in Europe, add a European mobile number via the second eSIM.
3. Turn off the US eSIM but keep it active.
4. Pros:
   1. You can receive calls to your US mobile number from friends back in the US via GV on the European data plan.
   2. You can send and receive iMessages and FaceTime calls from your US mobile number if you have a cellular connection.
5. Cons:
   1. You will need to keep the US eSIM active, even though it is turned off. This may incur a small monthly fee.

Option 2:

1. Forward your US mobile number to your Google Voice number before leaving the US.
2. Once you arrive in Europe, purchase a prepaid SIM card from a local carrier.
3. Pros:
   1. You will likely save money on international roaming charges.
4. Cons:
   1. You will only be able to send and receive iMessages and FaceTime calls from your US mobile number if you have a cellular connection.

Which option is best for you will depend on your individual needs and budget.

Additional tips:

• Be sure to check with your US mobile carrier about their international roaming rates and policies before you leave the US.
• If you are using a prepaid SIM card in Europe, make sure to purchase enough data to cover your needs.
• Consider using a VPN to protect your privacy and security when using public Wi-Fi networks.
