eSIM stopped working while abroad

[Ad60]

Hi all. 
I am using a Sky Mobile (Ireland) eSIM on my iPhone 16. 
I am currently in Japan and my eSIM stopped working around 2 weeks ago and is still not working. 
I tried to re-install the eSIM but it does not activate. 
I cannot request a replacement eSIM as the verification process attempts to send a verification code to the broken eSIM (I have no other Sky Mobile numbers to send the code to).
Last week I got in touch with Sky over WhatsApp and they were to try call me within 48hrs on another phone to try and resolve my problem. I didn't get any call from them. 
Would anyone have any advice for me to try resolve this? I don't return home for 2 more weeks and already missing my phone number for 2 weeks has been difficult. 
Thanks in advance for any help.

AIUI Japan is no longer supported for roaming.

Thanks for your reply.

You prompted me to check the Tariff Guide, and I see now that Japan is no-longer there.

The Tariff Guide was updated 20-Feb-2026, which coincides with around when my eSIM stopped working.

I don't understand why 3+ agents on the WhatsApp chat didn't tell me that Japan was simply no longer supported.

Unfortunately this means I will need to change provider.

Thank you again and have a nice day.
