I already have an active sim with my phone account but they've sent me a secondary sim. Will that charge me twice for the two sims although I only need one. Or can I cancel one of them when the new one is activated?&nbsp;</P> Sun, 18 Jan 2026 20:53:08 GMT https://helpforum.sky.com/t5/Sky-Mobile/Additional-Sim/m-p/5193584#M282992 k26- 2026-01-18T20:53:08Z https://helpforum.sky.com/t5/Sky-Mobile/Additional-Sim/m-p/5193596#M282993 <P><a href="https://helpforum.sky.com/t5/user/viewprofilepage/user-id/4594610">@k26-</a>&nbsp; Any deals are normally for a new sim/number.&nbsp; If you have had your old sim for 12 months or more you can port that number out to a PAYG provider then port it back to the new sim as you can't port between Sky sims.</P> Sun, 18 Jan 2026 21:05:52 GMT https://helpforum.sky.com/t5/Sky-Mobile/Additional-Sim/m-p/5193596#M282993 GD1 2026-01-18T21:05:52Z
