hi - I’ve been using this prepaid number (o2 my prepaid L) for about six months now, and I usually only use it for data / WhatsApp.
Recently I noticed I couldn’t send SMS messages to anyone (I can receive them from friends and 2-factor Auth services). I also notice that all phone calls go direct to voicemail, I never even have the chance to pick it up!
Can you check to see if there is an account / SIM configuration issue blocking it from being able to send SMS or receive voice calls? I have enough credit in my account (€ 24.59).
Thanks!
