Please read carefully: Using an incorrect type of SIM will void the warranty.
Cradlepoint modems are designed to accept 2FF and 4FF SIM cards, depending on the model. SIM cards other than the 2FF or 4FF types will not work correctly in Cradlepoint modems. If a SIM card other than the 2FF or 4FF types is inserted into a Cradlepoint modem, it may damage the modem or become stuck.
See the Quick Start Guide for your product to determine the type of SIM and specific instructions for installation.
Important: Activating a Cradlepoint XXXLP6-NA router on the Sprint LTE Plus network requires an ISIM type SIM. For more information on this use case, see this Stackoverflow thread titled What is the difference between ISIM and USIM? (Cradlepoint assumes no responsibility for information in external links.)
The dimensions of 2FF SIM cards are 25.0mm x 15.0mm x 0.76mm. It is possible to resize Nano or Micro SIM cards to 2FF dimensions using a SIM adapter. However, Cradlepoint cannot guarantee correct modem operation if a Nano or Micro SIM is used with an adapter.
See your router's Quick Start Guide for specific instructions on your device's SIM card size, orientation and installation.
