Step 1: Clear your SMS inbox. A full SMS inbox will result in a failure to receive any other SMS messages.
Step 2: Restart your phone and ensure that your telco signal is of acceptable and reliable quality. A poor network signal may result in not receiving any SMS.
Step 3: Check your smartphone's security program/app to determine if it is unknowingly blocking out these messages in the background. Traders may want to temporarily disable such programs/apps when submitting the withdrawal request.
Step 4: Contact your telco to determine if your mobile plan has been stopped/suspended/blocked for any particular reasons resulting in failure to receive any new SMS.
Step 5: Swap your SIM card into another slot (dual-sim smartphones) or insert your SIM card into another smartphone and try again.
