E25b was a variant of E25 that sent messages in Arabic, while still sending the preamble in English. Only known ID's were 835 and 837. Ceased when E25 switched to pre-recorded female voice in 2007.

The message structure was slightly different as well:

Here, the second group and the last but one are the same. The first two digits of the first group, when inverted, give the serial number, and its last two digits give the amount of 4-figure groups in the message. In the English messages, the repeated group is the third and the last one, and the serial/group count one is the second.

The groups were first read as two pairs with inverted digits, due to ordering of numbers in Arabic language, then individually.

The ID's used by E25b are still active and now recieve traffic from regular E25.
