Is there any alternative to fixed monthly billing for business mobile contracts?
Pay-as-you-go allows you to control pretty closely how much you pay for your business mobile phone service, but the per-call charges are generally higher and only worth it if your call volume is light. You also will not benefit from any special offers. Figure out your anticipated calling and texting volume and then ask the major business mobile phone providers for price quotes based on that volume. Comparing quotes is the best way to get the best deal.
