Yes you can cut the sim down to size with a sim cutter
Cut the sim out and file it down (nano sims are thinner) a bit and you're fine.
The other options are getting a nano sim for it you can go to a VAR and get one and have them activate it for you or order a sim off ebay or amazon or wherever else you get sim cards and activate it yourself online since it has you confirm any changes online you should be able to verify if it's going to drop udp.
I went with a sim cutter and a set of sim adapters if you get any sim adapters be careful with them! they can very easily bend and or break the pins off the sim reader in the device.
You reqeust them to igve you a new full size sim card and then you cut its yourself
get one of these and cut the sim cards
I bought one of these when my wife setup her Nexus 5 on H2OWireless

Feels sturdy, works well. I would offer to meet you and cut it, but honestly once these beer wear off I'm not going to want to. :)
