It depends on whats your purpose of the insurance, if only to satisfy the OA requirements, the min is around USD 200+/year with AXA. But dont plan on using it for actual medical benefits, as deductible is very high.
If u r planning on a actual usable insurance, than it depends on yr age and any pre-existing conditions.
it depends on what you need and your budget. For top tier brand and model its better to get trade in @ US. Dont think any trade in program here, Its way cheaper with it.
If you only need a secondary phone just in case if main one die, non top model here is quite reasonable, my new secondary phone is about USD 200+.
