Depending on the country you’re sending to, not all Sender IDs are supported due to rules and regulations. Local restrictions are put in place by governing bodies. For example, in some destinations, only certain Sender IDs can be used (e.g. Alpha or international numeric).
SMSGlobal has routes in all countries; please create a ticket below to our support team to discuss your Sender ID options further, or refer to the knowledgebase section on Laws and Regulations.
