How many sms apps are you running in your phone?
Please read this confirm you have done all this .......
When a user sends a text message (SMS message) to another user, the message gets stored in the SMSC (short message service center) which delivers it to the destination user when they are available. This is a store and forward option.
An SMS center (SMSC) is responsible for handling the SMS operations of a wireless network.
When an SMS message is sent from a mobile phone, it will reach an SMS center first.
The SMS center then forwards the SMS message towards the destination.
The main duty of an SMSC is to route SMS messages and regulate the process. If the recipient is unavailable (for example, when the mobile phone is switched off), the SMSC will store the SMS message.
It will forward the SMS message when the recipient is available. source
Hence, You must know the address of the wireless network operator's SMSC in order to use SMS messaging with your mobile phone. Typically an SMSC address is an ordinary phone number in the international format. The SMSC address is pre-set in the SIM card by the wireless network operator, which means you do not need to make any changes to it but it may not be entered into your sms app, hence you need to enter it manually
How do we enter SMSC manually?

Open Go SMS pro and touch menu in your phone > touch settings in Go sms pro > Touch advanced panel > scroll down to SEND setting and touch > scroll down to Enabled customized SMSC and TICK > than Touch Customized SMSC number and ENTER YOUR NETWORK provided sms center number in international format (meaning + countrycode & center phone number , its like +63918xxxxxxxx)

For MMS setting
