Do you sell a service or products to customers in different countries?
If you do not have actual offices or shops in these countries, it might be difficult for your customers to contact you.
Customer support by email and live chat is great, in some cases though a phone call solves a question or problem much faster.
Virtual phone numbers for local customer support
With international virtual phone numbers you can offer your customers local phone numbers in their country. Calls to these numbers will be forwarded to any number you want.
So no need to have an office there or an actual phone. Put your international numbers on your website, email signature, where ever you want and show your customers that you care about them.
Think globally, act locally.
