Send large number to arduino via bluetooth


I'm trying to send a large number (ex: 1234567890) to arduino via bluetooth client.
Recieve from arduino it's ok the same number or other number.
From the phone to arduino is not possible, the value recieved in the arduino is not the correct one.
Using the example of 1234567890 arduino recieves 138.
Is there any limititation?

thank you.

How did you send the number of the app to the Arduino?
The easiest way is to send it as text.

The point of this is to store a value in the phone to resend to arduino when it's needed.

How can it be sent as text?


Thank you so much @Juan_Antonio . It solved the problem.
