I recently renewed my membership and noticed the APN settings showing Tesco Mobile under MMS. The specifics:

Name: Tesco Mobile

APN: tescomobile.liffeytelecom.com

MMSC: http://mmc1/servlets/mms

MMS proxy:10.1.11.19

MMS port: 8080

MCC: 272

MNC: 11

APN type: mms

I'm wondering if this will have any impact on receiving texts or calls, as 4G-internet seems fine for now.
