iQOO is a performance-focused sub-brand of Vivo (BBK Electronics). The brand launched in China and is primarily a CN-market product. Global Edition variants of recent flagship models like the iQOO 15 support eSIM, but CN ROM variants (the dominant version in China) do not.
Key Takeaways
- iQOO 15 Global Edition: eSIM supported.
- CN ROM variants: NO eSIM hardware — iQOO is predominantly a China-market brand.
- Confirm "Global Edition" before purchasing an eSIM.
- One eSIM active alongside one physical nano-SIM (not Dual eSIM).
Does iQOO Support eSIM?
On Global Edition variants only. The iQOO brand is primarily sold in China as CN ROM without eSIM hardware. Global Edition models are sold in a limited number of international markets. If you purchased your iQOO in China or through a Chinese importer, it is almost certainly CN ROM.
Confirm your model at Settings → About phone → Model. "Global Edition" or an international suffix in the model name confirms eSIM capability.

Troubleshooting iQOO eSIM
"Add eSIM" option missing: Almost certainly CN ROM — iQOO is primarily a China-market brand. Check Settings → About phone → Model. CN ROM includes CN suffix. If confirmed Global Edition but option is absent, device is carrier-locked. Contact your carrier.
eSIM installed but no data abroad: Settings → Network & internet → SIM card & mobile network → select Roamix eSIM → set as default data SIM → enable Data Roaming. Toggle Airplane Mode on/off.
QR code scan fails: Must be on Wi-Fi. Roamix QR is single-use — contact support for replacement. Use manual SM-DP+ entry as fallback.
"eSIM not supported on this device": CN ROM hardware. No software update or ROM flash will add eSIM to CN ROM iQOO hardware — the chip is absent.
