Is Giffgaff a good network?

Giffgaff is a Mobile Virtual Network Operator (MVNO) which means it uses O2's mobile network to provide its mobile coverage, but it's also owned by O2 and was launched in 2009.

In our most recent customer service poll, Giffgaff scored 4/5 based on 1000 votes.

Does Giffgaff offer Sim plans for bad credit?

Giffgaff doesn't carry out credit checks when you apply for one of its Sims. You can then choose to purchase a monthly bundle (minutes, texts and data) or choose its 'traditional' PAYG tariff which charges you for each minute, text and MB of data you use.

The cheapest Giffgaff Sim

The cheapest Giffgaff Sim costs £6/month and it currently offers unlimited minutes & texts and 2GB/month data. It's a one-month contract so you can cancel anytime. See cheap Giffgaff Sims.

Can I keep my mobile number if I switch to a Giffgaff Sim-only deal?

Yes, you can keep your old mobile phone number. If you're moving from another network, you'll need to text 'PAC' for free to 65075 to request your PAC (porting authorisation code). You will need to provide this to Giffgaff which should move your number over within one working day.

Can I get 5G enabled Giffgaff Sims?

Yes, Giffgaff offers 5G on all of its Sim plans. However, be aware you'll need a 5G-compatible phone too.
