Get 50% off each additional 1pMobile Unlimited Family SIM. The first SIM costs £25 every 30 days and each additional SIM costs £12.50 for the same period. Two lines therefore cost £37.50 every 30 days. If both would otherwise be on separate £25 Unlimited plans, that saves £12.50 each time the bundle renews.

How much does the family bundle cost?

The discount applies from the second line onwards. Three SIMs cost £50 per 30 days, four cost £62.50, five cost £75, six cost £87.50 and seven cost £100. 1pMobile advertises no quantity limit for additional SIMs. To work out your total, start with £25 and add £12.50 for each extra SIM. Compare that figure with what everyone currently pays before you switch.

If two people both need unlimited data, the bundle costs £37.50 instead of £50 for two standalone Unlimited plans at the advertised rate. If one of those people uses only a few gigabytes, compare the bundle with buying a single Unlimited SIM and a smaller data plan for the second person. The lower-priced plan may give that person all the data they need.

How to get the half-price SIMs

Follow the offer link to 1pMobile and choose the Unlimited & Family bundle. Select the number of SIMs you want and confirm that the order summary shows £25 for the first line and £12.50 for each extra line per 30 days. The saving is built into the bundle price, so you can claim the deal without entering a voucher code. If you already have a 1pMobile account and want to move several existing lines onto one bundle, check how to do that with 1pMobile before placing a new order.

What each SIM includes

The Unlimited bundle includes UK data, calls and texts. 4G and 5G are included, with actual coverage depending on your device and location. Check coverage for the places where each person regularly uses their phone, such as home, work and the route between them. The plan renews in 30-day periods, so renewal dates can move through the calendar month. That matters if you prefer to line up household bills with a fixed payday.

1pMobile says it may slow speeds in busy locations if use exceeds 500GB in a boost period under its Unlimited fair use policy. Roaming is included in eligible European destinations, subject to a 14GB cap per boost and the provider’s roaming terms. Check the destination and allowance before travelling if you expect to use maps, video or tethering regularly while away.

Who is this offer best for?

The bundle is worth comparing if at least two people regularly use enough mobile data to want Unlimited. It can suit a household where one person streams on the commute and another uses mobile data for frequent video calls or hotspot access. If your household mainly connects over Wi-Fi, look at recent data use on each phone first. Comparing the whole household cost is more useful than comparing the percentage discount on one line.
