This post can be answer for some of your unanswered questions. Do you want to have a UK phone number, or want to get it with free incoming? If I am asking right question then this can be a right post.
You can get a free UK number if you are in India, Pakistan, Canada, Turkey and China.
To get a UK number you do not need to download anything and also you do not need a credit card verification.
To get started go to this Spikko Facebook page and select your country in left sidebar tab and click on “Click here to get a number”. A form will be open, you have to fill that form properly, as your name, password, target number.
After filling the form you have to click on “call me”, you will receive a phone call on your phone, when you receive the call, a lady will tell you your pincode three times, you have to fill that in pincode field and click on “Finish Registration”.
If you want to get the call on another number other than target number, you have to check the box that is below “Call me“ button.
After finishing registration you will be suggested to go to Spikko website. There you will see your UK number. So when someone will call you on your UK number, you will receive call on your target number.
You can receive call from 40 countries. You can make calls using your UK number but you have to buy balance.
