What will be the best way to use the Dual SIM for travel? 1) Get your primary phone plan on the embedded SIM and leave the real SIM tray available for local travel sims? 2) Keep your primary number on a physical SIM and dynamically subscribe to different carriers while traveling on the embedded SIM? I guess it kind of depends on how many carriers will offer easy to subscribe to short term plans on the embedded SIM. Option 1 would give access to all international carriers, but would require a visit to a local store to set up a plan. Option 2 could be the easiest, but may have limited (or no) local carriers and plans might be more expensive than the real SIM options. Any ideas how this will shake out?
