Best Buy via eBay offers the
Cricket Wireless BYOD SIM Activation Kit for GSM Phones for
$1.99. (
Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to avoid a $5.49 shipping fee. That's a buck under our February mention, $8 off list, and the best price we could find. It includes a SIM card, micro adapter, and standard adapter.
