Recently, we needed to make some changes to our mobile phone plan. As it's a business plan, we called our account rep who alerted us to a neat trick.
If we transferred services from a competing carrier, we could get our first three months on the new deal for free. In order to do that, the account rep suggested that we buy some cheap SIM cards from another carrier, transfer our services to that carrier on the cheapest possible pre-paid option and then transfer them back to the original carrier the next day, thus garnering the three month discount.
Do you have any other neat tricks for scoring discounts? Share them in the comments.
