A SIM lock, simlock, network lock, carrier lock or (master) subsidy lock is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks. This is in contrast to a phone that does not impose any SIM restrictions.
Caveat emptor is Latin for "Let the buyer beware". It has become a proverb in English. Generally, caveat emptor is the contract law principle that controls the sale of real property after the date of closing, but may also apply to sales of other goods. The phrase caveat emptor and its use as a disclaimer of warranties arises from the fact that buyers typically have less information than the seller about the good or service they are purchasing. This quality of the situation is known as 'information asymmetry'. Defects in the good or service may be hidden from the buyer, and only known to the seller.
The International Mobile Equipment Identity (IMEI) is a numeric identifier, usually unique, for 3GPP and iDEN mobile phones, as well as some satellite phones.

Seller financing is a loan provided by the seller of a property or business to the purchaser. When used in the context of residential real estate, it is also called "bond-for-title" or "owner financing." Usually, the purchaser will make some sort of down payment to the seller, and then make installment payments over a specified time, at an agreed-upon interest rate, until the loan is fully repaid. In layman's terms, this is when the seller in a transaction offers the buyer a loan rather than the buyer obtaining one from a bank. To a seller, this is an investment in which the return is guaranteed only by the buyer's credit-worthiness or ability and motivation to pay the mortgage. For a buyer it is often beneficial, because he/she may not be able to obtain a loan from a bank. In general, the loan is secured by the property being sold. In the event that the buyer defaults, the property is repossessed or foreclosed on exactly as it would be by a bank.
