Can you keep your same SIM card if you change your data plan
@Buzz52 if you have ordered a new sim only if you can persuade sky to apply the new plan to your existing sim
there is no obligation on sky's part
If you upgrade without ordering a sim you keep the existing one
Yes, changing the monthly data plan allowance doesn't affect the SIM card.
@Buzz52 As long as you are just upgrading your current plan and not ordering a new sim/plan you can keep the old sim.
