I have just upgraded from an iPhone 6S+ to an 8+ and was sent a new SIM card.
The old card was already 4G compatible, so I was thinking that I would just keep it and swap it in to the new phone, which is working great.
However, when I checked the 2 SIMs, the old one is labelled 4GPP2, and the new one is 4GPP3.
Is there any actual difference in the cards and would I gain anything at all from the 4GPP3 card, or should I just leave it as is?

As it's all working fine, I'd leave it as is.
Keep the new SIM in case it's needed in the future.
