Frequently asked questions

How do I use a mobile phone voucher code?
Copy the code from this page using the "copy" button, click "Use offer" to visit the retailer in a new tab, add your phone or contract to the basket, and paste the code into the discount field at checkout. Apply the code BEFORE you finalise payment - most retailers will not add discounts retroactively.
Are these voucher codes verified?
Every code listed comes directly from official affiliate feeds provided by the retailer themselves (Awin). We refresh the list once every 24 hours so expired codes drop off automatically. We do not list user-submitted or unverified codes.
What is the difference between exclusive and standard voucher codes?
Exclusive codes (marked with an orange "Exclusive" tag) are deals the retailer offers only through select partners like ours. Standard codes are available across the web but still verified active. Exclusive codes often save more, but tend to have shorter expiry windows.
How often are voucher codes updated?
Our system pulls fresh codes from retailer affiliate feeds once every 24 hours. Expired codes drop off automatically. New codes typically appear on this page within a few hours of the retailer activating them.
Why doesn't my voucher code work?
Most code failures come from one of four causes: (1) the basket does not meet a minimum spend or product requirement, (2) the code is for a specific phone or category that does not match your selection, (3) the code is for new customers only, or (4) the code recently expired - check the "Ends" date shown on each card. The retailer's terms appear at checkout; read those before assuming the code is broken.
Can I combine multiple voucher codes on one order?
Most UK mobile retailers (Carphone Warehouse, Mozillion, Oppo) only accept one promotional code per order. Some retailers let you stack a code with cashback or a trade-in offer - check each retailer's terms. The "Use offer" link takes you straight to the right place.
Are voucher codes the same as cashback?
No. Voucher codes are upfront discounts you enter at checkout - the savings reduce the amount you pay immediately. Cashback is money returned AFTER the order completes (sometimes weeks later) via a third-party tracking site. Voucher codes are simpler: code in, savings out.
