Sim card on chinese android - Android Q&A, Help & Troubleshooting

Hi everyone,
I had been using a phone Huawei Y635 (rooted, RR 5.8.4) for several days with my mobile operator (Vodafone), surfing in 3g and 4g with no problems, when yesterday I had to insert another mobile operator sim card (3 Italia, which is based on UMTS system) and the phone didn’t detect it.
So I did some tests that I will list below:
1. I inserted the same 3 sim card in another phone (Lumia 925) and it worked perfectly;
2. I tried a second 3 sim card – that usually works in a Samsung A5 – and, again, the Y635 didn’t detect it;
3. I did a counter-check by inserting another mobile operator sim card (Tim) in the Huawei Y635 e this one had been detected at the first shot.
4. I checked the sim cards were well inserted in their lodgings and I also tried to use both the sim slots (it’s a dual sim phone), but nothing changed.
5. Finally, I went to a 3 Center, and you can imagine what kind of assistance those girls could have given to me...
I know that some Chinese phones had problems with 3 operator, such us IMEI problems, etc., but I understood it’s a problem that shows only in terminals which set Mediatek processors.
The Y635 has a Snapdragon processor. I don’t remember the code, but it’s not Mediatek.
Do you have any idea about it?

anyone can help me?

"Cannot connect for an unknown reason" with every ROM I tried

I bought a used Orange UK TG01, unlocked it with an unlock code, then flashed some cooked ROMs. Voice calls work perfectly, but a "Cannot connect for an unknown reason" comes out immediately when I use anything that needs a data connection. This even happens with a stock Hong Kong WM6.5 ROM.
Is my TG01 defective? I flash ROMs with SDDL+ and my microSD card is a Transcend 8GB microSDHC Class 6. The only things I haven't tried yet is using a microSD (<2GB) card and using the pin shorting method to flash ROMs instead of using SDDL+.
I'm in Hong Kong and my mobile operator is PCCW 3G. All connection settings are correct. The same settings and SIM card work with my HTC TyTN II.
Try this....
Change your sim card with your friends or your wife's. I am thinking that your phone company is the problem. I had the exact same problem with my phone here in Japan. Said something just like your message. So I swapped the sim card with the sim card in my wife's phone and boom... my phone worked perfectly. I had to call my phone company over and over and over again, then they said that they will "refresh" my phone account and it took three days. So... just try a different sim in your phone, the problem you are describing is EXACTLY the same as I experienced. No data connection, but SMS(I think.. I am not sure, it happened to me three years ago) and phone works fine.
Check it out, tell me what happened when you swap sim cards?
-Kilihari.
Luckily my operator happens to be carrying out some network upgrades which requires me to get a new SIM card from them, no phone calls needed.
I got my new 64K SIM card and bam, everything works perfectly now! The chip on the SIM card is smaller than my previous SIM card.

[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.

SIM recognized but no service

I have an unlocked Lenovo Golden Warrior Note 8/A936 2 gb ram dual sim phone. Its also rooted. In my country there are 2 network providers. I have a SIM for both. The phone recognizes both of the sim cards and even labels them by their network name but only picks up the service for one of the network providers. Ive made sure both sims are good. They both work fine in my Samsung Galaxy Note 4. Trying to figure out what could be wrong with the Lenovo as it won't pick up any service for that SIM card.
Ive tried:
both sim slots and still only one recognized.
removing the working one and the other still wont find service
Factory resetting
Manually/Automatically finding the network. Manual search doesnt find the ine i want to find
Switching from 2g,3g,4g preferred types
Any idea what could be wrong?
wrong lte/4g channel
Maybe your provider uses a for the handy not usable channel and the sim is a lte/4g only! So the device doesn'T recognize the sim, Iguess. I'm sorry, bad luck

Magic-sim circuit does not work on samsung note 3

The magic sim circuit that I bought recently does not work. I've bought it because I wanted to enable two different mobile phone accounts with two different SIM cards on my samsung galaxy note 3. Problem is that only the SIM card placed on the first slot of the phone is detected. The second one is not recognized. When I turn the phone on and I click on the DUAL sim app created by the magic-sim,the error message is always "no service available". I can give you more details...

Honor 8 behaving like it's locked?

I've a problem with my new Honor 8. I have a Vodafone contract SIM in slot 1 and when I went abroad to St Lucia I bought a local SIM (flow) for slot 2 and switched over to activate that in the settings. A Simple process i have not done before on this phone but have on my previous Motorola Moto G4. The problem is the only network the phone could see was the other carrier on the island (Digicel) who Vodafone use if I used world traveler plus at £6 a day. The SIM worked fine in my friends Samsung J4 so the SIM was OK. I tried the Flow SIM in SIM1 and it still didn't work.? again it detected the Digicel network but not flow? I tried auto search and manual search?. Actuated roaming and mobile data. Re-started the phone countless times. It's like the phone is behaving as if it's locked for Vodafone only (which is what the guys in the flow shop said?) but I bought the phone from Huawei direct through Amazon as unlocked?
It should be simple and straightforward?. I've checked and re-checked the settings many times
Any ideas?
