https://community.48.ie/t5/Joining-48/Sim-activation/m-p/74916#M5122 Hi, I was transferring my Tesco Mobile number to my new 48 SIM. I started the number transfer through the 48 SIM activation/QR code. After doing this, my Tesco SIM stopped working and my 48 SIM is also showing no service. When I try to enter my Tesco number again on the 48 website, it says “Sorry! This MSISDN already exists.” Please check the status of my port and activate/complete the transfer to my 48 SIM. I cannot receive SMS on my Tesco SIM anymore.
