Instabridge does not offer an eSIM for Luxembourg that provides a phone number or SMS capability. All eSIMs sold by Instabridge for Luxembourg are data‑only plans. Travelers can still use the data connection to access VoIP applications such as WhatsApp, Telegram, and iMessage for voice and text, but the provider does not supply a local number or SMS service.
Because formal telephony is not included, those who need a local phone number or mandatory SMS must look at other providers or consider third‑party virtual number services. Notably, access to VoIP apps can depend on local restrictions, so it is advisable to confirm that the apps you rely on work in Luxembourg before purchasing an eSIM.
