No. Openline eSIMs configure the APN automatically. Do not manually enter an APN — leaving it blank is correct.
If you already typed one in and things are broken: iPhone → Settings → Cellular → Openline → Cellular Data Network → Reset Settings. Android → Settings → Network & internet → SIMs → Openline → APN → delete any custom APN and let it auto-configure.
