An unlocked eSIM-compatible iPhone can keep the usual number available while a Jamaica eSIM handles mobile data. The important step is assigning each line a clear role before arrival.
Quick answer: Add the eSIM on reliable Wi-Fi, label it Jamaica, select it under Cellular Data, enable Data Roaming for that line and turn off Allow Cellular Data Switching. Keep roaming disabled on the primary SIM.

Open Settings > General > About and look for an EID. Check Carrier Lock on the same screen; it should show “No SIM restrictions.” Model and regional differences matter, so verify the exact device before purchase.
Add the Jamaica eSIM
Connect to stable Wi-Fi, open Settings > Cellular/Mobile Data and choose Add eSIM. Scan the supplied QR code or follow the manual installation information from the order.
Label the new line Jamaica. Installation and plan activation are not always the same event, so follow the activation timing supplied with the selected plan.
Select the data line
Under Cellular Data, choose Jamaica. Turn off Allow Cellular Data Switching so the iPhone does not silently use the primary SIM when reception changes. Open the Jamaica line and enable Data Roaming.
Leave roaming disabled on the primary line. It can remain active for its number if required, subject to the home operator’s charges for calls and SMS.
Test after arrival
Turn off Wi-Fi and open a webpage to confirm cellular data. If it does not load, check the active line and Data Roaming, then try aeroplane mode once. Leave Network Selection on Automatic.
If manual APN entry is required, verify data.esim. Do not delete the installed eSIM unless NoveSIM support instructs you to do so.

FAQ
Which iPhones support a Jamaica eSIM?
Support depends on the exact model, region and carrier-lock status. Confirm an EID and Add eSIM option before purchase.
Should Data Roaming be on?
Yes, enable it for the Jamaica travel eSIM and keep it disabled on the primary SIM.
Should Allow Cellular Data Switching be enabled?
No. Turning it off helps prevent the iPhone from using the home SIM for data unexpectedly.
Can I keep iMessage and WhatsApp on my normal number?
Usually yes. Adding a data eSIM does not require changing the number registered to those services.
Final Recommendation
Install and label the Jamaica eSIM before departure, then assign it to Cellular Data with Data Roaming on and data switching off. Test over cellular data after arrival without deleting the profile if registration is delayed.
