International businesses and businesses with a global reach need to stay in touch with mobile workers who crisscross the globe on their behalf. For a long time these companies have given employees two or more phones to use: one for use while working at their main office and another for use in each country in which each employee travels. The most accomplished business travelers could require several phones, each of which would need to be manually loaded with essential contact information. Cell phone international plans turn international mobile communications into something more manageable.
Cell phone plans that work internationally allow users to carry the same phone everywhere they go. All they do is remove the domestic SIM card from their phone and then install a special SIM card from their international service provider. Their phone is now equipped to seamlessly operate in more than 200 countries. The international SIM card enables the phone to work with voice, SMS, voicemail and data without the need to change phones, services or SIM cards upon crossing international borders.
Although cell phone international plans sound like an expensive proposition, they are actually more affordable than most people expect because they connect to local cell phone networks. Because networks see phones with these special SIM cards installed as local devices, they are charged local rates. This means that cell phone international users get better coverage at lower prices than what many typical international business travelers pay.
New SIM card technology called the multiple international mobile subscriber identity (multi-IMSI) gives mobile phones the ability to assume multiple identities without swapping cards or phones. Businesses pay the multi-IMSI provider to create and maintain those identities so a phone stays connected regardless of what country it is located. By creating a way to have seamless, scalable, carrier-grade interconnects throughout the world, international mobile service companies have transformed the way businesses regard international travel.
Rather than juggling SIM cards or phones, travelers relax as a unique auto-provisioning system keeps their phone in contact with the latest local networks. When profiles and coverage maps change, the international cell phone service provider can remotely update their SIM cards via OTA update technology. Thus, the identities present on an international SIM card are always operational through the nearest cell phone towers. This keeps all associated cell phone numbers active and accessible at all times. Global companies (or companies that plan on becoming global) should equip all their employees so their business can continue operating seamlessly, regardless of where their employees happen to be.
