You are using 2 phones with 3 eSIM?
Two Poco X7 Pro phones with 4 physical SIM cards, Singtel SIM Only without China Roaming data, plus the above-mentioned three physical SIM cards. Poco X7 Pro does not support eSIM.
Eight S$8 4G plan (Starhub 4G network) -- China Mobile, 3GB China roaming data, free voice roaming.
CUniq S$9,9 4G plan (Starhub network) -- China Unicom, 20G China roaming data.
SIMBA S$12 plan -- China Telecom, 18GB China roaming data, free voice roaming.
I do not think I need so much data, just for testing.
BTW, I will also try out the LinkLAN eSIM adapter + giga travel eSIM -- still a physical Sim to the phone. The roaming partner is probably the same as giga (China Mobile + China Unicom. This is just for testing. giga travel eSIM is not cheap, 5 day 3GB at S$7, 5 day 5GB at S$9.70, 30 days 10GB at S$18.70, etc).
giga eSIM for China, from giga Shopee store, at S$1.86
