The Swedish operators Telia and Tele2 have their own versions of the router B593. Both are clones of the B593u-12, which are sold in Germany also. From the start, users had problems when attaching non-DC short circuited external antennas. Telia responded to the critizism and offered a new firmware which allows for the user to choose manually in the web interface if an internal or an external antenna should be used. This firmware is locked to Telia which only offer LTE 800 and 2600. Tele2, on the other hand, never reacted to the problem and has not offered any new firmware. This operator uses LTE 900 and 2600. The only remedy are the adapters which contain a small resistor (Widerstand) and thereby makes the router shift automatically to external antennas. These "Spezialadaptern" are fairly expensive. Question 1: can they be bought in Germany and at what price? Question 2: is there any unlocked firmware available for the B593? The clients of Tele2 are the ones which have the greatest need for a solution but the problem is of course the use of LTE 900. (I posted earlier questions regarding diagnostics and reading RSRP and RSRQ in the B593. I now have personal experience with these routers and can confirm, that the Swedish versions allow for exactly the same readings as the German versions.) Question 3: Is there any news of a possibility of locking the B593 router to a specifik LTE band? It should be mentioned, that the Dovado firmeare version 6.1 allows for locking the E392 and E398 modems to a specific band. It is probable, that the same could be done in the B593, if only Huawei allowed for it. Bitte auf Deutsch oder Englisch antworten/Answers welcome in German or English Grüsse Jonas/ Many thanks to this forum for offering access to international participants with questions relating to the German experiences with LTE hardware. I am convinced that many Russian internauts will find the info valuable, now that LTE 800 and 2600 are quickly rolled out in Russia. AVM should market a Russian version of the Fritzbox AVM6840. The market could be huge.
