The present invention relates to a call forwarding device and a method using a text message, and more particularly to a call forwarding device and a method for sending a text message from abroad and receiving a domestic call.

The mobile phone international roaming service used to date is a type of service in which a mobile phone service company has a roaming agreement with a partner country company and provides a certain procedure and an additional fee when the customer requests it. Automatic roaming is a service that uses the same mobile phone that the customer used to go out, and rental roaming is a service that rents the mobile phone whether or not the customer joins before going abroad.

This is because the call quality is relatively good and mobile, so there is the convenience of free use of the call, and in the case of automatic roaming, there is no change in the phone number, so it is possible to make a call without any inconvenience for domestic callers.

However, in addition to the international roaming fee, the domestic country pays a fee equivalent to that of an international call, which is expensive, and a domestic user must pay a fee for roaming. In addition, the use of the service may be limited depending on the telecommunication company's telecommunications network (including domestic and party's) or local circumstances. In case of rental roaming, mobile phone rent must be paid separately. In addition, although the call environment may be convenient for structural reasons, the burden of the most sensitive fee is too great for the user.

In addition, in the form of separate telecommunications service providers, equipment leasing and call intensive services are provided to customers by low-cost discounts on telecommunication facilities (including network) or call usage fees by contracts for service provision by backbone network operators or counterpart telecommunication companies. It is a new telecommunications company that pursues operating profits by discounting rates. Self-owned equipment operators are operators who own their own equipment or networks, and mainly use their own networks or equipment to provide international calls to customers at low cost. Occasionally, the contractor uses the network or equipment of the main network operator as needed. This is a cost saving effect of owning a facility, providing customers with good call quality and relatively low call charges.

Their use method is to service customers at home and abroad or use prepaid communication card and use as much as the corresponding amount by using the separately assigned call line access number. Internet phone users use ID and password in the same form as the conventional dial pad. Make an international call after connecting.

This is a very low price and can be used freely when necessary when using a prepaid communication card. However, the call quality is relatively lower than that of the main network operator. The environment is relatively limited. In addition, it is inconvenient because the call button has to press the number button relatively more than the main network operator when using the telephone.When the congestion or discount rate time zone of the international internet network does not match with the other country, depending on the usage time, the connection may be poor. There is also a problem that the probability of fraud can not be ignored when using a telephone service provider's prepaid card to make international calls.

In particular, the international automatic roaming service, which is more vulnerable to the reality that the business area is set as the global stage these days, is becoming a big inconvenience for the frequent business operators (trade business, walking prizes, etc.) running in the field. There is an urgent need for an international mobile roaming system that is simple in procedure, has good sound quality, is low in cost and easy to use.
