Quick answers.
I landed but my eSIM is not connecting. What should I check first?
Set mobile data to the travel eSIM, set Cellular Data APN to data00.telnyx, set roaming for your country, then toggle airplane mode for 30 seconds.
Should I turn off my primary SIM?
You can keep it on for calls, SMS, and login codes, but turn off data roaming on your primary SIM if your home carrier charges roaming fees.
Can travel eSIMs receive SMS verification codes?
Travel eSIM plans are data-only unless a plan clearly says otherwise. Keep your primary number active if you need bank codes, carrier calls, or Wi-Fi Calling.
Can I move an eSIM to another phone?
Most eSIM QR codes are one-time use and bind to the first device that installs them. Contact support before deleting a profile or changing phones.
