Iphone Sim swap or use old one

[Anonymous]

I have just got my new Iphone 6s plus, I have a question regarding my sim card. I received notification yesterday that my account is now on my new iphone tariff. I have a nano sim card in my current phone, so should I just put my existing sim card into my new iphone or do a sim swap with the one that came with the phone?

Thanks

If you want to keep your number and your existing sim card is a nano sim then just put it into your new phone. keep the other one as a spare @Anonymous

Thanks, that is what I wanted to hear as I didn't really want to go through the sim swap process!

If it all works fine then you should be OK

I put my old sim in from my Samsung S3 to my new Note. All worked well. I only swapped it as the Note is a 4G phone and the S3 sim was just 3G. Best of luck anyway...

As long as you did an upgrade and your tariff has switched over you can carry on using your old sim.
If it's a new or additional contract you will need to activate the new sim.
