Testing Your Phone Numbers Globally

Why would I want to test my phone number. Surely it just works?

Great question but faults happen, international carriers turn off phone numbers for no usage and there is a list as long as your arm why a phone number may not work.

Once you have purchased a phone number and tested it before you place it into any adverts or websites, most companies just expect them to work. With reliable carrier like ourselves and other tier one providers this is usually the case for 99% of the time but things can go wrong. Generally advertised phone numbers are often forwarded to a call centre or location where calls get picked up by agents. Some numbers get huge amounts of calls and others may only get sporadic calls. If you have a number that gets hundreds of calls a day you will generally know when a service goes down. If not, your number could be down for weeks before you realise. Here are some examples of why a phone number may not work:

  • The local in country carrier has switched it off for low or no usage

  • The regulations in country have changed and you are no longer compliant meaning that the carrier is forced to switch the number off

  • You have moved office and forgotten to amend the call forwarding on the global phone number you advertise

  • There is a network fault in country

  • There is a network fault on your answering location

  • The IVR you set up years ago may still forward to a section of your business that is closed down or moved

  • The list can go on

Now you know why it’s a good idea to test a phone number perhaps we should tell you how much it costs.

If you would like your number tested from a landline or mobile (cell) in country then these tests will cost £20.

What you receive from us post test

Once we have tested your number we will send you the below information:

  1. The time and date of the test call made
