iD Mobile APN Settings for UK

Runs on Three network 4G LTE

Last verified: July 2025

iD Mobile is a UK MVNO operated by Currys (formerly Dixons Carphone), one of the UK's largest electronics retailers. iD Mobile runs on Three's network, giving it access to Three's 4G coverage and, on some plans, Three's 5G network. iD Mobile is particularly popular as a budget option for customers buying phones in Currys stores. iD Mobile's APN is simply id — one of the shortest APNs of any UK carrier. It shares Three's MMS infrastructure, so the MMSC URL and proxy are the same as Three's. iD Mobile currently offers 4G as standard, with 5G available on selected plans. No authentication credentials are required.

iD Mobile APN Troubleshooting

Remove and reinsert your SIM. Try resetting network settings on your device. iD Mobile phones sold through Currys may come with pre-configured settings — check the box or documentation for the configuration SMS code.
The APN for iD Mobile is just the two letters id — no 'mobile', no '.co.uk'. This short APN catches many people out. Confirm it is selected and mobile data is on. Check your iD Mobile account for active data.
iD Mobile shares Three's MMS setup: MMSC is http://mms.um.three.co.uk:10021/mmsc, proxy is mms.three.co.uk, port is 8799. If your phone requires an IP address for the proxy, try leaving it blank and using only the MMSC URL.
Contact iD Mobile support through the iD Mobile app or website. Ask them to disable OTA configuration if settings keep reverting.
Verify MCC 234 and MNC 20 (Three's network identifiers). Wrong MNC is the most common cause. Set Protocol to IPv4/IPv6 for best compatibility.
