Accordingly, international roaming service among mobile communication companies has become common Subscribers are utilizing.

However, many international roaming service users do not receive roaming incoming calls as well as originate international roaming calls due to excessive service charges, or abandon their use by themselves. In addition, local incoming calls are also referred to as international roaming incoming calls, It is a fact that you pay a fee.

In the meantime, the voice call service, which combines mVoIP (Mobile Voice over Internet Protocol) technology in the Internet environment, has been developed for the reason of very low cost and has been absorbing a considerable part of international telephony demand. However, The user's dissatisfaction was caused by the sound quality problem.

In addition, the mVoIP voice call by the international data roaming service is rather more expensive than the general voice international roaming phone, and it is inconvenient to use it only in the free Wi-Fi area.

In addition, it is possible to rent low-cost inter-country Internet line provided by a telecommunication service provider to implement an inexpensive international calling function by VoIP (Voice over Internet Protocol) method. However, In the case where the telephone number can not be operated, there is an inconvenience to use because it is possible to transmit only in the country, that is, in the local area.

In addition, in a shaded area where mobile communication infrastructures are not available due to a lack of a mobile communication infra in foreign countries, even if an international roaming service is received, many users may feel inconvenience of lack of communication because they can not make calls.

On the other hand, when using the Universal Subscriber Identity Module (USIM) purchased in a foreign country between foreign trips and foreign trips, it is possible to make relatively cheap international calls and calls between local subscribers. However, There was no way to make a call until I gave the number.

In addition, there is no way for a person working in a company or organization to make an international call using a cheap international private line owned by a company or an organization using a landline telephone or a mobile communication terminal from outside the office It is true.

That is, in the conventional international roaming system, roaming between systems or networks having different specifications may not be technically possible or may be set by an operator, but it is inconvenient to use.

On the other hand, the conventional international roaming service is convenient because it is automatic roaming, but many people avoid international roaming charges because they judge that the international roaming charges are excessive, and there are many users who are uncomfortable because they can not receive calls to foreign landline telephones.
