[Q] Ainol Poseidon/Numy AX1 3G Tablet - Not detecting any SIM card

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.
