Alcatel OT-871a



The Alcatel OT-871a is a QWERTY bar phone released by Alcatel in 2012.

It was sold under AT&T's GoPhone prepaid plan with several features to boot, but was still considered basic by the early 2010s.

Variants

 * OT-870a: Unbranded version.
 * OT-871S: Another unbranded version(?)

MediaTek MRE support
The OT-871a's MRE support is not documented anywhere on the manual, but attempting to run MRE .vxp applications on the phone does show an MRE logo.

Unfortunately, no MRE games or applications are known to have been developed with the 220x176 resolution in mind. The MRE functionality is there, it just cannot be tested further as MRE apps with a different resolution result in an STR_ID_AM_FAIL_TO_START error.
