Can I use a global eSIM for phone calls and texts?

Most global eSIMs are data-only, requiring VoIP apps like WhatsApp or Skype for calls. Exceptions include: Airalo Discover+ (provides Austrian +43 number with calls/SMS from $15), MTX Connect (MTX Number subscription for calls to any phone number, SMS service), and KnowRoaming ReachMe (voice calling feature). Keep your home SIM active for receiving bank 2FA codes.
