Mobile provider, T-Mobile had recently corrected an error in their advertisement which offered 12 months of free mobile service instead of 1 month to some of its customers. However, the mistake has been rectified now. A SIM card with 500 texts, 250 minutes and 500MB of data per month for a year was announced in the erroneous advertisement.
Customers who got the offer also received an email from the company admitting their mistake but agreed to give it for the same price although international calls and premium rates are not included. T-Mobile tweeted about the mistake and mentioned about the correction. It also added that one year free mobile service offer will be applicable to those who have already signed up for it.
