Looks the the best bet is this:
Infocomm Media Development Authority: Telecom Licensing System (IMDA-TLS) Database (
NOTE THAT All Mobile Phones to be used in Singapore MUST BE REGISTERED into this IMDA-TLS database in order for it to be used with a Singapore Telco SIM Card). Malaysia's equivalent would be
Scientific and Industrial Research Institute of Malaysia (SIRIM) Database for the curious and works the same way for Malaysian Mobile Phones.
*** WARNING: GEEK ZONE***
Right now, the 5.5-inch HTC U11 is registered both in IMDA-TLS and SIRIM (under model '2PZC300'). So the next step is to see if U11+'s model number will be logged on both databases once it is approved (FYI: Model Number for U11+ are designated '2Q3Fxxx' compared to U11's '2PZCxxx' model number designation,
source for this info.), hence the wait for it would be to have the unit registered into the database FIRST before we can see signs of an impending release, hopefully soon... and judging from the appearance of the U11+'s pages in many of the HTC sub-sites including SG's own, chances are that the device may already be under IMDA Registration here and awaiting approval before sales dates can be cemented down, or sometimes not at all (like LG's V30 (H930) which failed and ended up not being registered into the IMDA-TLS database, hence the registration of the device H930DS, which happens to be the V30+ that can have its release confirmed).
