home $50 Referral Program Shipping USPS – United States Postal Service There are multiple shipping options for the the post office. None are guaranteed. I repeat, none are guaranteed. First Class Mail – this is a regular #10 envelope with first class postage. Delivery time is usually 5-7 days. Free Priority Flat Rate Envelope – delivery time is estimated at 2-3 days but seems to be taking more like 3-5 days. It has tracking. $10 Priority Overnight Express – It says overnight but in my experience it is take 2 days. $29.99 Fed Ex Standard Overnight is $34.95 ( at this time they seem to be running on time but I do not guarantee delivery) Unless you request, your SIM will be shipped via First Class Mail. We ship daily and provide tracking if needed.
