Before I visited Barbados I purchased the international roaming package (voice/data/text). I am receiving and sending texts on my Samsung S4 with no problem and able to use my data. I can make local calls but when I call to check my voice mail or make an international call; it advises me that outgoing calls or international calls cannot be made from my phone number. I have tried using the '+' before the number but this does not work.
I purchased the same plan last year and do not recall being unable to make calls.
Any suggestions or ideas on what can be going wrong?
