Hello,
in Uk a brought a Galaxy-S (T-mobile) and unlocked it. Now I'm back in Italy and I put my old SIM card. The Phone works, except for 3g, edge or any mobile connectivity. I think there is two options:
- The phone is still locked.
- My sim is very old (from 1999), may be no more compatible with 3g.
How do I find out which is the case and how I solve that?
Thanks guys (girls too).
No network
Hi m8
Could you please check your imei number, I did exactly the same.
I bought my sgs on firmware 2.1 & unlocked it via free unlock tool, I then messed with some new firmwares. Recently tried to sell my phone as unlocked but when buyer put their sim in, It shows a signal but no data network connection.
After messing around with different sims i did a check & noticed my firmware is some stupid 04999????
Regards
Mark
What does that mean?? Is it related to IMEI somehow?? What should I check about it? How do I fix that? I've 2.2 by the way
Hi i really need a bug help. I bought my s3 Lte 4G in singapore last month. i activated my LTE simcard from globe but when it was activated I cannot open my Mobile Data. everytime i try to open mibile data it says "Insert sim to access network services" I was able to use my H+ signal when i still have my regular simcard and ive talked to globe and they said that they did not released any LTE s3 (Thats why im looking for a way to use this here). I know some s3 LTE users can use their globe sim but it is the s3 LTE unit with the antenna , mine dosent have any. please i really do need ur help. By the way im from the philippines ang globe user.thankyou
Hi,
I also have the same problem. I bought the S3 LTE i9305. I thought it would be compatible with the Globe sim(Philippines) since the S4 works with it. When I used the LTE sim in the i9305 it can be used to call/text but when accessing data/network it displays the "Insert sim" message. Non-LTE sim works fine.
Anyone have any idea on how to fix this?
Thanks in advance.
Usual wrong modem wrong CSC.

I got mine working. I read somewhere that the an update for the i9305 fixes this so I factory reset my s3 and updated via kies. After the update I now have 4G as signal.
Just a question though, my friends with iphone are getting LTE, and mine is 4G. Same service provider. Am I still not getting LTE?
s3 lte help

Hello everyone,
I have Mi 9 M1902F1G 128gb with MIUI global 11.0.4. I am living in France and using Bouyuges telecom, recently when I come to work my phone loses network connection related to simcard. No calls, no 4G, no 3G nothing absolutely. There is a cross sign sometimes on network bar, then sim card activation process starts but no connection. Even I cannot send an sms. This is a new problem. I have been using this phone with same sim card for approximately for a year.
Thanks in advance

Since you don't tell us what actions you already have taken the most obvious is to pull out the sim card and clean it. If this doesn't help, contact your operator to get a new sim card. Everything you say indicates that your problem is one with the sim card or the operator and has nothing to do with the phone.

Have you tried with VoLTE disabled?
Also, by preferring network type 3G or even 2G, instead of 4G.
Maybe you recently got some some 4G/3G micro-station at work with the band not supported by phone
Edit: You could also try to inspect by Network Cell Info Lite, Net Monster, Net Monitor or similar apps available from Playstore
Hi all,
I've just purchased a Verizon G998U with cracked front screen and back and found that the phone is google locked - FRP Locked. According to the seller, it was Verizon unlocked prior to the sale. Tested the phone with my local Malaysian SIM Card and I was getting signal from it prior to getting the screen replaced and FRP unlocked.
I have managed to get the FRP Lock removed and a factory reset later allows me to setup the phone properly with my own Google Account but when i'm putting in my Malaysian Sim Card, it says that this is not a Verizon sim card.
Any ideas on why this is happening? Will an sim unlocked phone be reverted back to a locked phone after FRP lock is removed?
Thanks in advance
Ask the seller for the unlock code used before
Noted miravision, what do i do with the unlock code then? Putting in my Malaysian sim card and rebooting the phone does not ask for any unlock code.
Depending on whether the seller used an official unlock authorized by Verizon or used unofficial means, your seller should help you further in good faith
Noted with thanks, miravision. I will check with the seller and will update once i get a feedback from them
Update on the testing done to the phone. Didn't managed to get anything from the seller. But did some interesting testing with the phone. I've got 2 sim cards with two different provider in Malaysia - Celcom and Yes.
Flashed the phone with the U1 XAA software and managed to setup the phone with Yes sim card with VoLTE running and Internet working. As for Celcom SIM card, no signal at all and tried playing around with Samsung Band Selection App, managed to get the sim to connect intermittently with VoLTE and Internet working. Removal of sim and reboot of the phone will sometime changes the Celcom SIM to no signal at all and manual searching of the Celcom network also doesn't show the selectable network and only shows Yes 4G network.
So from the testing above, can i presume that the phone is sim unlocked? If it's unlocked, why can't the other sim from Celcom can't be detected consistently?
Anyway, the telco info is as below
YES - LTE Band 20 (800 Mhz), Band 38 (2600 Mhz), Band 40 (2300 Mhz),
VoLTE Support
Celcom - LTE Band 1 (2100 Mhz), Band 3 (1800 Mhz) , Band 7 (2700 Mhz) - VoLTE Support.
Hopefully can get some insights on what is actually going on.
Thanks in advance
