Upon receiving a call failure response from the telecommunication network the system is configured to transmitting a second communication request to the target user device through a second communication channel, wherein the second communication request comprises a target authentication key. The target user device is configured for generating an authentication response upon authentication of the second communication request based on the target authentication key. Further, the system is configured to transmit an activation signal to the target user device through the secondary communication channel for deactivating the airplane-mode and activate the first communication channel upon receipt of the activation signal. ## Claims ### Claim 1 A system for controlling airplane-mode in a user device, the system comprising: a memory; a processor coupled to the memory, wherein the processor is configured to execute programmed instructions stored in the memory for: transmitting a connection request to a telecommunication network for connecting with a target user device over a first communication channel; receiving a call failure response from the telecommunication network, wherein the target user device is in airplane-mode; transmitting a second communication request to the target user device through a second communication channel, wherein the second communication request comprises a target authentication key, wherein the target user device is configured to: maintain a set of authentication keys in a local repository, wherein each authentication key, from the set of authentication keys, is associated with a registered device from a set of registered devices, compare the target authentication key with the set of authentication keys to authenticate the second communication request, and generate an authentication response upon authentication of the second communication request; receiving the authentication response from the target user device through the second communication channel; and transmitting an activation signal to the target user device through the secondary communication channel, wherein the target user device is configured to deactivate the airplane-mode and activate the first communication channel upon receipt of the activation signal. ### Claim 2 (depends on 1) The system of claim 1, wherein the first communication channel is a telecommunication channel. ### Claim 3 (depends on 1) The system of claim 1, wherein the second communication channel is short range communication channel, wherein the short range communication channel is one of a Bluetooth communication channel or an RFID communication channel. ### Claim 4 (depends on 1) The system of claim 1, wherein the authentication response is generated when the target authentication key matches an authentication key from the set of authentication keys. ### Claim 5 A method for controlling airplane-mode in a user device, the method comprising steps of: transmitting, by a processor, a connection request to a telecommunication network for connecting with a target user device over a first communication channel; receiving, by the processor, a call failure response from the telecommunication network, wherein the target user device is in airplane-mode; transmitting, by the processor, a second communication request to the target user device through a second communication channel, wherein the second communication request comprises a target authentication key, wherein the target user device is configured to: maintain a set of authentication keys in a local repository, wherein each authentication key, from the set of authentication keys, is associated with a registered device from a set of registered devices, compare the target authentication key with the set of authentication keys to authenticate the second communication request, and generate an authentication response upon authentication of the second communication request; receiving, by the processor, the authentication response from the target user device through the second communication channel; and transmitting, by the processor, an activation signal to the target user device through the secondary communication channel, wherein the target user device is configured to deactivate the airplane-mode and activate the first communication channel upon receipt of the activation signal. ### Claim 6 (depends on 5) The method of claim 5, wherein the first communication channel is a telecommunication channel. ### Claim 7 (depends on 5) The method of claim 5, wherein the second communication channel is short range communication channel, wherein the short range communication channel is one of a Bluetooth communication channel or an RFID communication channel. ### Claim 8 (depends on 5) The method of claim 5, wherein the authentication response is generated when the target authentication key matches an authentication key from the set of authentication keys. ### Claim 9 A computerized device having a processor and a non-transitory memory, the non-transitory memory having embodied thereon a computer program for controlling airplane-mode in a user device, the computer program comprising: a program code for transmitting a connection request to a telecommunication network for connecting with a target user device over a first communication channel; a program code for receiving a call failure response from the telecommunication network, wherein the target user device is in airplane-mode; a program code for transmitting a second communication request to the target user device through a second communication channel, wherein the second communication request comprises a target authentication key, wherein the target user device is configured to: maintain a set of authentication keys in a local repository, wherein each authentication key, from the set of authentication keys, is associated with a registered device from a set of registered devices, compare the target authentication key with the set of authentication keys to authenticate the second communication request, and generate an authentication response upon authentication of the second communication request; a program code for receiving the authentication response from the target user device through the second communication channel; and a program code for transmitting an activation signal to the target user device through the secondary communication channel, wherein the target user device is configured to deactivate the airplane-mode and activate the first communication channel upon receipt of the activation signal.
