Questions about the iPhone 12 Pro and eSIM
Answered from its spec sheet and from today’s prices.
Does the iPhone 12 Pro support eSIM?
Yes. The iPhone 12 Pro supports eSIM and runs 2 lines at the same time, except the version sold in mainland China, which only takes physical SIM cards. Add a travel eSIM for data abroad and keep your usual SIM for calls and texts.
How many eSIMs can the iPhone 12 Pro use?
The iPhone 12 Pro runs 2 lines at the same time (1 SIM card + 1 eSIM).
Can I keep my phone number abroad with the iPhone 12 Pro?
Yes. Keep your usual SIM on for calls and texts and use the travel eSIM for data. Turn data roaming off on your usual line, so it does not charge you.
Which travel eSIM should I get for the iPhone 12 Pro?
Any data eSIM works on an unlocked iPhone 12 Pro. The right one depends on the trip: on October 22, 2026, for a week in Thailand with everyday use, the best price was Jetpac at $9.50. Compare your destination with the tool above.
Does the iPhone 12 Pro have a SIM card slot, or is it eSIM only?
Yes: every version of the iPhone 12 Pro has a SIM card slot (2 nano-SIM), plus eSIM.
Can I use two eSIMs at the same time on the iPhone 12 Pro?
Not two eSIMs: one eSIM and one physical SIM can be active at the same time.
Why is my eSIM not working on the iPhone 12 Pro?
Check four things in Settings › Cellular: the travel eSIM line is turned on, it is selected for Cellular Data, Data Roaming is on for that line, and your iPhone is not locked to a carrier. Then restart it.
What if the eSIM is stuck on “activating”?
Activation needs an Internet connection: stay on Wi-Fi for a few minutes, then restart the phone. Many travel eSIMs only connect once you land, so “No service” before you leave is normal.
