'''Removable User Identity Module''' ('''R-UIM''', usually pronounced as "R-yuim") is a card developed for [[cdmaOne]]/[[CDMA2000]] ("CDMA") handsets that extends the [[GSM]] [[Subscriber Identity Module|SIM]] card to CDMA phones and networks. To work in CDMA networks, the R-UIM contains an early version of the [[CSIM]] application. The card also contains SIM (GSM) application, so it can work on both networks. It is physically compatible with GSM SIMs and can fit into existing GSM phones as it is an extension of the GSM 11.11 standard.<ref>{{Cite web |url=http://www.3gpp2.org/Public_html/specs/C.S0023-C_v1.0_060530.pdf |title=www.3gpp2.org C.S0023 |access-date=2007-05-01 |archive-date=2007-09-27 |archive-url=https://web.archive.org/web/20070927182055/http://www.3gpp2.org/Public_html/specs/C.S0023-C_v1.0_060530.pdf |url-status=dead }}</ref> <br />

This [[(U)SIM interface|interface]] brings one of the main advantages of GSM to CDMA network phones. By having a removable identity card, CDMA users can change phones while keeping their phone numbers by simply swapping the cards. This simplifies many situations such as phone upgrades, phone replacements due to damage, or using the same phone on a different provider's CDMA network.<br />
<br />
The R-UIM card has been superseded by [[CSIM]] on [[Universal integrated circuit card|UICC]]. This technique allows all three applications (SIM, CSIM, and [[Universal Subscriber Identity Module|USIM]]) to coexist on a single smartcard, allowing the card to be used in virtually any phone worldwide that supports smart cards.<br />
<br />
The CSIM application, a port of R-UIM functionality to the UICC, is defined in standard.<ref>[http://www.3gpp2.org/Public_html/specs/C.S0065-0_v2.0_081202.pdf www.3gpp2.org C.S0065]</ref><br />
<br />
This form of card is widely used in [[China]] under the CDMA service of [[China Telecom]] (which was acquired by [[China Unicom]] in 2008). However, it is also used elsewhere such as [[India]], [[Indonesia]], [[Japan]], [[Taiwan]], [[Thailand]], and the [[US]].<br />
