Sim Swap and Smart Switch

[paulmills]

Hi - not sure if it matters but I am moving from an A50 to an A53 and have a new O2 SIM so can't just use the same one as before. Should I use the new SIM in the A53 and do an O2 SimSwap straight away and then the Smart Switch afterwards, or doesn't it matter what order I do these in? Thanks

You should probably do Smart Switch first, and then the o2 Sim Swap
