my friend bought me CAT B15 from US,(i live in Indonesia).when i use my cat B15 i realize that the phone cannot connect to 3G, because when i use the same SIM card to another android it can connect to 3G. and the dual SIM card cannot work too.i checked in setting menu, ther is no option for dual SIM card and for 3G.the contact support ask me to send it back to the distributor, but i think it's not make sense. it's so far away from indonesia.anybody can help me?
Same problem here. When mobile data is switched on, no matter which card is in which space, phone tells me I have inserted SIM card in wrong slot and the connection speed will be limited.
Hello Brothers,
I got Ainol Poseidon AX1 tablet from some seller on Aliexpress. I wanted to set this up as my Car entertainment system.
Was very happy with the overall performance of this Tablet until i connected a CDMA/GSM SIM Card.
I never used a CDMA SIM card and have not tested it with either GSM SIM card upon receiving this tablet.
This tablet does not detect any SIM card. Used Airtel GSM SIM, Tata Docomo CDMA SIM in India, Hyderabad and nothing works.
Contacted seller who is from China and he says that AINOL does not detect SIM cards provided by Telecommunications company(GOD KNOW WHAT HE MEANT BY THAT). Wondering who else can provide a SIM card.
- Tried factory reset - no luck
- CDMA sim card of other providers too - nothing worked.
Is any one using Ainol Numy/Poseidon AX1 3G Tablet in India? Do you use any SIM card for it?
I request forum members to please help me out in getting this thing working.
Thanks in advance.
Regards,
Santosh Keerthi

Hello
A friend solved the problem?
Solved for me
I had that problem with my tablet.
In my case, i'm using a sim card from an operator using 1900Mhz for 3G, so i have to use gsm.
The tablet connects for a few seconds and then disconnects, with a sim error. After a while, it connects again and disconnects,....
I guess that the problem is the tablet trying to connect to the 3g network, then , as it don't work, it disconnects.
Using Mobileuncle Tools, go to engineer mode-> engineer mtk ->telephony-> sim1/sim2 and select the bands you want to use (the ones supported for the tablet).
Then , in telephony->network selecting you can choose gsm/wcdma, gsm only,...
As the 3G band from my operator is not supported in this tablet, i set gsm only and it's working fine.
I'll try a sim from other operator with a supported 3g band and i'll tell you if it's working with 3g or not.
Final Solution
If your problem is not the band in USA (Ainol AX1 works with 2G: GSM 850/900/1800/1900MHz and 3G: WCDMA 850/2100MHz) and you get "Invalid IMEI" try this:
1. You need a couple of old useless but clean (not blocked by IMEI, not stolen) GSM cell phones
2. Write down IMEI numbers of the old phones (typing *#06# or watching under battery)
3. In Ainol AX1, write *#*#3646633#*#* in dialer. You will see a new menu. Goto connectivity > CDS Information > Phone 1 > write AT+EGMR=1,7,"1ST_IMEI_HERE" > send AT command after completion message reboot your phablet and repeat for phone 2 but with command AT+EGMR=1,10,"2ND_IMEI_HERE".
4. Voila! You have the power

I face the same problem. Running with the original ROM both GSM and WCDMA sim cards were reset frequently. I had to switch to flight mode and back to make them seek for mobile network and connect again for sometime.
I flashed Ainol Numy AX1 2013.10.20 V1 2 GB Rom CWM Recovery hoping to solve the issue but no luck. Now are almost all the time with no signal. After flashing, IMEIs were kept the same. After first boot tablet was connected very quickly and that was all. 3G connection is mandatory for daily use. It was the reason to buy this tablet.
Has anyone tried different valid IMEIs ? Does this trick work? .
I got same problem but it is only sometimes, no frequently. It is not significant. I installed this ROM

Since i had this problem making 3G/2G useless i finally replaced the IMEI of sim2 with the IMEI of an old forgotten sonyericsson phone, and voila everything goes perfect now !! No resets and dramatically increased signal strength.
The only explanation i can give (i am not an expert) is that there was an IMEI identification issue with the carrier.
Dear Community , I’ve just bought a P9000 smartphone and I’d like to ask a question: as far as I know this dual SIM phone can not support 4G (or even 3G) when both SIM cards are inserted but to me the only way to have 3G or 4G capabilities is to insert the SIM card in slot 1 (the outer one, the same slot of t-flash memory expansion)… Is this behaviour normal? I thought that , with a single SIM card inserted, didn’t matter which slot was used to get 3G or 4G working on phone, and this is a severe issue because if you want 3G/4G capabilities you have to use slot 1 and therefore no more t-flash into the phone… Please, could you help me? I tried with engineering mode (BSPTelephonyDevTool) but no joy at all... Thanks in advance, best regards.
I have always had my sim (Three UK) in slot 2 as I use a 60GB SD card and I have had no problem getting 4G tbh. Altho the 4G connection was never really as fast as I expected & very ocassionally it wouldnt attched to a 4G connection in an area with 4G (but this was kinda very very rare)
Sorry I dont have a solution to your issue, but on a side note I have just installed the Andriod 7 Beta to test it out and I can confirm that the 4G is outstanding on that, even the 3G is way faster with a much much better signal - better than I have ever experienced on any other ROM to date. (same with the GPS, its spot on)
What network are you on & what Stock ROM (I'm assuming your using stock with you just buying it) are you using? the latest Stock?
Thanks for prompt reply, to be honest the phone belongs to my sister... Anyway, the P9000 is on TIM (Telecom Italia Mobile) network operator and android version is Marshmallow 6.0. At the moment the issue still remains, I think that she'll be waiting for Nougat 7.0 to come on OTA...
Hello everyone !
First i have to tell you sorry because i don't know everythings about the phone rooting and all of that but i know some!
I bought a phone in Thailland , the True Smart 4g Max 5.0 and i would like to use it in France, i watched everywhere on the web
and i have try some many tutorial but i can't root my phone and i can't install new rom,
when i put my sim (Operator FREE Mobile) in the slot 2 (sim 2g) i got full bar network and a E next to it (Edge i thinks), so i try to call and the phone tell me sim 2 is locked pls use sim 1 but the sim 1, its write slot 1 True H and nothing appear when i put my sim in.
I read on the web we have maybe not the same frequence network Thailland/France? Is t possible to change the frequence of my phone ?
Thanks you for all your futhur response
Hello everyone.
I have one or two little questions about the phone. I have this phone since July and I would like asking about few f*cking issues. I have the H930DS with the Boombox ROM and have faced the same issues with the lastest 21* Official ROM.
SIM A France with Roaming ok - SIM B Switzerland. I live in Switzerland.
------------------------------- DATA SIM A - Calling with SIM B -----------------------------
-> no internet while calling
-> sms cannot be send with SIM B
-> poor signal with sim B, very oft no signal
------------------------------- DATA SIM B - Calling with SIM B -----------------------------
-> internet ok while calling
-> sms cannot be send with SIM A
-> Very good signal in SIM B, poor signal with sim A
My Problems with signal quality is also when I make no call. I don't understand why is so... Make no sens. I have oft the problem with no signal in SIM B and when I choose SIM B for Data, signal is automatically better....
Faced you this problems ?
Thanks you.
Anyone with other/previous Dual SIM devices can tell a same story ?
The most seldom Android devices have dsda (dual sim dual active), afaik the H930DS is dsds like many devices (dual sim dual standby)
https://gadgetstouse.com/news/dual-sim-dual-standby-and-dual-sim-dual-active/8985
That at least partially might be able to explain it,
also living at the border and roaming with 2 different country SIMs is supposed to be quite bothersome I read back some time.
No idea if it's supposed to have improved
Thanks, I had no idea about this active or standby mode. This is annoying... But that's explained not the problem with signal strength... I have no idea how is it possible.

what connection tech / speed are you using for each different SIM ?
if I remember correctly there was also an issue with only one SIM being capable of using 3G or LTE at a time and the other being limited to 2G (or similar)
so that could be one explanation of it.
Haven't looked into that kind of issue yet since I don't have a dual SIM device
