bbob, Thank you for your review.
To answer so of your remarks.
service life
We impose a network charge to cover our operator fees.
This is a charge that we receiver every month to keep the number live with the telecoms operator.
When you have a customer that receives hundreds of inbound "free roaming" calls, but never makes any outbound calls. We still get charged to keep that number live. Hence we have to charge a network fee.
Customer who make calls as well as receive free inbound calls, We will not charge this fee. So when we say "Customers who purchase call credit within 90 days of there expiry date will not need to pay the network fee and all credit will be rolled over for the next 365 days"
This rule is flexible and at our discretion. We look at customer usage.
Rates
As this is a global sim card and our customers are globally. It is easy for our customers to convert US Dollar to there home rate. We do however have a comparison on our rates page giving a example of the cost in euro's and in GB pound Stirling.
As for the slight difference in back office rates compared to our website rates. Our website rates is rounded up to the nearest cent. This is for technical reasons for our online calculator to work correctly
Every customer has to look at each site for there best option.
We don't charge a daily or connection fee
We have 24/7 customer support (telephone & email) unlike other's that only offer 9am to 5pm, Monday to Friday or just email support.
I think most people look at all these options and that why we have had a very good year and especially this Christmas.
My golden rule.
Keep the customer happy !
