I considered both the Android option and the mobile hotspot option, neither effectively solved the problem of using the local SIM for voice calls and providing access to my full contact database (which is currently stored in iCloud).
If you have no need for voice calls, or your address book, or have your address book stored on a more cross platform friendly service, then either of these solutions will work for you!
