X Factor fans have been told they will not be able to vote by text for this weekend's final, which is expected to feature the finalists performing with their mentors
Text votes returned to the show only two months ago after an absence of several years.
But now show bosses have confirmed there will be no more of the 35p-a-time votes for the final, which is reported to see judges Kelly Rowland, Tulisa Contostavlos and Gary Barlow singing with their acts.
It's been suspended due to the shorter cut-off period for votes, which mean any delays on mobile networks could entail thousands of wasted messages.
Text voting was suspended in 2007 after a number of problems with phone votes during live TV shows. But it returned in October and has been in place since then, including last weekend's semi-final.
However a message on the X Factor website confirmed there will be no texts for the final, featuring Marcus Collins, Amelia Lily and girl group Little Mix.
X Factor bosses explained: "Because The X Factor final includes a vote 'freeze' and therefore a shorter vote period, it is not possible for text voting to be offered, as delays can be experienced within the mobile networks at busy times which could result in text votes not being received within the period the vote is open."
Voting has caused problems for the hit ITV1 talent show in the past.
During the 2005 X Factor final, 13.9% of votes cast by red button and text arrived too late to be included, although it did not affect the outcome of the show. A 2007 report by auditors Deloitte found "serious technical issues" with red button and text voting in a number of ITV shows.
This year's competition will end with performances by Coldplay, Leona Lewis, JLS and One Direction.
