Yes, I'll admit that I'm kinda a Neanderthal when it comes to new technology but I'm a fast adopter once I'm introduced to a gizmo that has obvious utility. When I first started ice dancing the options were to either have the music played over the rink's sound system, a thing only done at our rink for competing skaters and only done one time per skater during a given Free-Style session--or alternatively, your coach could chase you around the rink with an MP-3 player in her hand or a boom box on her shoulder(!)--stylish coaches could do that with one hand, freeing up the other for handling the requisite over-priced cup of coffee. A little later on, one could some how wear a smart phone around one's neck with the sound high enough so that both you and your partner could hear the music. I figured with my history of taking big swan dives on the ice that I'd be buying a new smart phone on a weekly basis. Lastly, I've heard of people skating partnered with each combatant sharing one half of a pair of earbuds connected by wire to either an iPod or a smart phone. I hope to never see that--sounds like a train wreck just waiting to happen.
Now, most wearable Bluetooth speakers that I've seen up until Coach A. showed me one her brother gave her for Christmas didn't look all that practical. They dangled by carabiner clips or the like. Her little speaker is a Mifa F20. It is compacted and comes with a Velcro strap (however some Mifa speakers don't so it pays to check) that fits easily and snugly around one's arm.

Anyway, if you're looking for an on-ice music solution, even if the SIM card thing is a misunderstanding on my part, the pairing of your smart phone with this little speaker just might be the answer you're looking for.
