I recently purchased HTC One e9+ from UAE, and I live in KSA.
I'm a subscriber at Mobily (Etisalat in KSA)
The provider supports 2G / 3G / Lte TDD / Lte FDD
The mobile supports all the operating bands.
Few months ago all bands were allowed, hence I used to camp on 4G (TDD or FDD) freely.
Nowadays, the operator decided to reserve the 4G TDD network to fixed devices. to do so, they decided to block the IMEIs of the mobile phones which support both bands and allow only 4G FDD to be used by mobile phones.
- After that, I noticed that I rarely camp on 4G FDD, even though, all my friends with other mobiles can see 4G FDD normally.
- Moreover, I noticed that all e9+ and M9+ are suffering the same issue with Mobily and other mobiles like Samsung and iPhone are normally functional.
- After some traces and investigations, I discovered that the HTC Mediatek based devices prefer the TDD band and start registering as soon as it is available, once rejected because of blocked IMEI, the dumb device just marks all LTE technology as forbidden and never tries to register to the alternative FDD band, keeping only 3G forever.
- Snapdragon base devices tries access to any available LTE band, one by one, hence, it normally operates under the same conditions, like (M9, Samsung, iPhone…)
- If I am at a location with 4G FDD coverage ONLY (No 4G TDD tower) i have to toggle airplane mode to allow re-selection to start from scratch and be able to use 4G FDD, and if at any moment the dumb piece of metal tries to HO to 4G TDD, it gets rejection due to its IMEI and not just go back to 4G FDD, it forbids all the 4G tech and stays till the next restart on 3G.
The worst part is contacting HTC customer support, who provided no care AT ALL and just told me "We will consider this issue in future releases"
I know that they have some hidden codes which allow users to disable certain LTE bands and even change the band priority, but they preferred not to support and have no headache to support their suffering customers.
HTC is the WORST OF THE WORST EVER
