Default Any way to add name to Caller ID display when calling people from T-Mobile prepaid? - 08-06-2011, 19:57

When I call a landline from a landline in the US, the receiving party sees my name displayed on the Caller ID along with the number. From a TMO prepaid phone, either only the number is shown or a generic description such as "CELL PHONE 212". The phone is as registered as it can be - they have all my details. Is there any way to add the name so it will display?

Just discovered the following explanation about alphanumeric callerIDs on Wikipedia:
Quote:
When an originating phone switch sends out a phone number as caller ID, the telephone company receiving the call is responsible for looking up the name of the subscriber in a database. It is for this reason that mobile phone callers appear as WIRELESS CALLER, or the location where the phone number is registered (these vary based on which company owns the block of numbers, not the provider to which a number may have been ported). Additionally, nothing ensures that the number sent by a switch is the actual number where the call originated; telephone switch initiating the call may send any digit string desired as caller ID. As such, the telephone switch and, therefore, the operating entity must also be trusted to provide secure authentication.
So you can't do anything to make your name appear with the called party. It all depends on the called party's phone company which must have access to the caller's phone company database in order to get names for each number.


terminals: Samsung: Galaxy S5 DuoS (G900FD); BLU: Win HD LTE; Nokia: 1200; Asus: Fonepad 7 ME372CG; Huawei data: E3372, Vodafone R201, K3765, E1762;
postpaid: O2 on Business XL; prepaid: DE: Aldi Talk, Lidl; UK: 3; BG: MTel, vivacom; RU: MTS; RS: MTS; UAE: du Tourist SIM; INT'L: toggle mobile
VoIP: sipgate.de (German DID); sipgate.co.uk (British DID); ukddi.com (British DID); sipcall.ch (Swiss DID); megafon.bg (Bulgarian DID); InterVoip.com

It also matters what the database has for a number. On prepaid it may not have the same database as monthly contract subscribers. If that's the case all you'll get when a T-Mobile prepaid calls is the identification "cellular caller (name of operator.)


Current SIMs:

T-Mobile US (prepaid)
T-Mobile NL (prepaid)
Fido CA (prepaid)
Orange IL (prepaid)
