If you’re in the hunt for affordable cellphone service, you may want to check out Republic Wireless’ new offer.

Starting tomorrow, May 16, Republic Wireless will offer six months of free service when you activate a phone with its Bring Your Own Android Phone program. To qualify for this offer, you’ll need to order a Republic Wireless SIM card (no cost, you pay shipping) between May 16 and May 22, then activate your phone by June 6.
