Otono Networks today announced the launch of AlwaysOnline Wireless, a global LTE roaming network exclusively for iPads with Apple SIM. The roaming network will be available in 45 countries, but will expand to additional countries in the future.

AlwaysOnline will offer LTE data plans starting from $0.99 an hour for 15 MB, and users can pay by hour, day or megabyte. Otono CEO Emir Aboulhosn says that the company wants to offer short-term data plans for times customers "really need connectivity on-the-go" like if they need to "catch up on email in the car" or "get directions to their next meeting."

AlwaysOnline's roaming network is available in countries like Canada, Mexico, France, Germany, the United Kingdom, Australia, New Zealand, Israel, Japan, Saudi Arabia and more. However, the network's plans aren't available to the residents of the majority of the countries listed. The full list can be seen on AlwaysOnline's website.

Last year, Apple introduced the Apple SIM with cellular models of the iPad Air 2 and iPad mini 3 sold in the United States and United Kingdom. The Apple SIM allows users to easily move between networks, taking advantage of short-term data deals when needed. More recently, the cellular models of the iPad mini 4 and iPad Pro have included Apple SIM support. The Apple SIM can now be purchased in 13 countries.

Earlier this year, Apple agreed to a deal with mobile connectivity company GigSky to bring Apple SIM cellular data plans to over 90 countries. While GigSky offers short-term data deals in more countries than AlwaysOnline, the latter offers even shorter-term data deals, enabling users to purchase hour and day-long plans.
