Can you imagine switching to another cellular provider for your smartphone without having to go to a shop or wait for your physical SIM card to be shipped? Or traveling abroad knowing your phone will work and you won’t face data-roaming charges? Or using the same phone number on your smartphone, watch, car and even your refrigerator?

The Opus hotel in Vancouver made a somewhat shocking announcement last week. The hotel was ripping the landline phones out of its rooms and replacing them with iPhones. While that seems extravagant, it’s actually a rather brilliant plan.

The hotel, which already offers guests an iPad that can act as a concierge service, points out that offering guests, particularly international guests, an iPhone adds a lot of value. In addition to the value for customers, Apple’s free iOS management tools could make implementing such a program simple and relatively inexpensive – beyond the cost of the iPhones themselves anyway.

One of the challenges when traveling internationally with iPhone or iPad is handling data roaming. There are two reasons that it’s incredibly easy to end up with a large bill when traveling for work or vacation.

One reason is that iOS features and apps can use data without you realizing it (iCloud’s Photostream feature being a great example) – to avoid such issues, you can disable data roaming in the iOS Settings app. The second reason is that the costs associated with international data roaming are rarely spelled out well by carriers.

At least one carrier is hoping to change that. This week Verizon announced that it will be offering customers a new set of international data plans intended to make managing data roaming easier to understand and track.
