@Kikulinska You can use your old sim card, if it's the same size needed for your new phone. If your new phone is 5G capable, and you're in a 5G area, you can do a sim swap to the new sim, which will be 5G capable. If 5G isn't in your area yet, there's no rush. Just put the new sim card in a safe place for future use.
