When you are trying to send a broadcast message abroad (outside your country), you may find this error:
So, is it actually possible to send a broadcast message abroad?
The answer is YES! You are able to send a WABA broadcast message outside your country's region.
However, since Facebook enforced different pricing depends on which country you are going to send a broadcast to, you will need to buy the overseas broadcast quota. The price is varied, and you can check the pricing on WhatsApp Official Pricing Schedule plus USD 0.004 for each quota. If you have checked the pricing and agree to the terms, please contact your Account Manager to buy the overseas broadcast quota.
