Three Mobile is offering up to £250 cashback when customers switch to its network.
The telecoms giant is handing out the cash incentive on certain handset and SIM only plans between May 6 to July 7.
Exactly how much you'll get in cashback depends on the type of deal you take out with Three.
It goes by the type of device you get, as well as the data plan you'll be on. The maximum amount you could get is £150.
You'll get £250 if you switch to a deal with unlimited data, £200 for 100GB, £100 for 30GB, or £75 for 12GB for the following handsets:
- Samsung A22
- Samsung S21 FE
- Samsung S22 Ultra
Or for the following handsets, you'll get £200 for unlimited data or 100GB, £100 for 30GB, or £75 for 12GB:
- iPhone 13
- iPhone 13 Pro Max
- iPhone 13 Pro
- iPhone 12
- Samsung A13
- Xiaomi 12 Pro
Those who switch to Three will receive their cashback through a pre-paid Mastercard.
If you're planning on switching to Three, you should make sure you're not signing up to a contract you can't afford just because of the switching offer.
For example, an Apple iPhone 13 on Three with unlimited data costs £50 upfront, and then £52 a month for 24 months.
An iPhone 13 with O2 and 250GB of data costs £50 upfront and £40 a month for 24 months.
Always compare prices first to make sure you're getting the cheapest deal.

Andy Foy, director of marketing at Three UK, said: “With a record rise in the energy price cap and many other soaring household bills, we want to give something back to customers so that they can save money in other areas of their lives.
“By ensuring that switching to Three provides amazing value and is as simple as sending a text, we hope to help people where we can during these challenging times.”

How to save money on your phone bill
If you're out of contract, the first thing you should do is compare prices to see if you're getting the best deal.
You can compare prices using CompareTheMarket.com, Confused.com, MoneySupermarket.co.uk or Uswitch.com.
If you do spot a better deal and you're out of contract, you should be able to switch providers for free.
But if you're still locked into a service or you don't want to leave your current provider, then you could try haggling.
Haggling is never guaranteed to always work, but if you do pull it off, you could end up making huge savings.
Start by calling up the customer service centre of your current broadband provider, and then give them details of the cheaper deal you've found - and ask if they can match it.
If they say they can't match it, you could try telling them you're thinking about disconnecting to see if that has any more sway.
Those who are still in contract and are desperate to leave should also check how much they’d have to pay to leave early, as you may still save money if the deal you’ve found elsewhere is massively cheaper.
