Hi all,

I have a question to those using Rebel SIM or any TurboSIM type solution to unlock their phones.

Do you experience problems receiving calls using Rebel SIM/TurboSIM?

I am using Rebel SIM at the moment for my Iphone 3G and I did not realize it until recently that over the last month, I have not received any calls but been receiving SMSes to say that there were missed calls from many numbers. So, I called myself (I have two phones) and then it realized that it all the calls go to voice mail. Then I tested using the call forwarding function, and guess what? All calls were received at the forwarded number.

This is very weird.

a) I can call out (No problems)
b) I can use data (3G, GPRS and EDGE)
c) SMSes work

But cannot receive calls even when the signal is at full bar.

I am using Maxis with unlimited 3G package. I took out the SIM and it worked fine on my other phone.

Can anyone help me on this?

Appreciate that...

Thanks.

dude.. what is ur iphone3g from? which country? have u tried the yellowsn0w from cydia?

Contact the seller of your RebelSIM?

I have a colleague who bought an US iphone 3G, same problem as yours. He is using Maxis SIM.

What he did is to disable 3G, then receiving calls no longer a problem.

My advise is:

use software unlock instead, that works better.

I am using an official unlocked iphone 3G on Celcom with no problem for in and outgoing calls with or without 3G/HSDPA

hope this help

Hi Milky,

I am using an Iphone from Japan, its locked to Softbank and already on the Firmware 2.2.1.

Shoki,

Thanks for the advice, I wanted to do that.. .but had a bad deal with the seller.

chiacy,

I guess I will try that... the 2G method. See if there are any changes... will turn on the 3G when required.

Thanks all for the suggestions and replies...

Dev Team seems to be taking so long to break the 2.2.1 firmware :-P

ur firmware is 2.2.1 what is ur baseband ?

Sadly, my baseband is the 2.30.3 and I cannot revert back to the 2.28 version.

So, I am stuck and require the SIM unlocking solution instead of the software unlocking.

Hello..

yeah i got this problem too just realize also lol.. how come whole day no call coming in..

disable the 3g - can call out and receive call
enable 3g = can call out only..sms also hard come in .. so no other solution or other sim unlocker? im using Rebel

Is better to off 3G network cause of turbosim, gevey or rebel all similar function.

as for me, when im in my hometown in kampar perak, i also cant receive call when someone calls me, sms ok, i believe the maxis tower in kampar somehow not pacth/update properly in order to use with maxis 3G sime card in, when i turn off my 3G signal i can receive call etc, there was no problem when im in here in shah alam or other place,

i using sg set iphone and my brother also using aus iphone( last month ) and now using UK set also got problem only in our hometown...

anyway TS where is the place you encountered this problem? how about trying to use it at other places and see how it goes, example at your work/study places.

Hi, my friend recently updated his Iphone 3G to 2.2.1 firmware, which inturn updated his baseband to 02.03.30 or something (the one that is not supported by yellowsn0w). Has anyone heard of a downgrade yet?
Is there a turbo sim (hardware unlock) for this firmware? if so, how much and where can i get it?

Read the link below.

2. iPhone HARDWARE Service Provider

try this link it may help you

http://thebigboss.org/2009/04/14/phaseband...in-your-iphone/

in cyndia also got type 'downgrade baseband'

however all of this will work if your using Bootloader 5.8 in the simple word your phone manufacured b4 september 2008.

dear all sifus..need some advice from you. i have recently bought a Iphone 3G 16G.
FYI it's using turbosim to run with the version 2.2.1 (5H11).
The modem firmware is 02.30.03.
The iphone is an Australia set

i am able to detect my maxis line (no problem with call, incoming/outgoing and even SMS incoming/outgoing) but the problem is when i turn on my 3G, it will search and somehow or rather, it will not be able to detect the maxis.
i would need to turn off my 3G and redetect the line only then i will get the maxis coverage.

how can i enable the 3G with my maxis still on?

do you have any advice on this?

Please help...

if you really want my advice, i would suggest that you pay the unlocking fees (since it is an OZ unit) through the proper channel.

it saves you a lot of time and hassle in the near future.

just a one time "pain" (monetary and time wise), for a permanent "gain"

will it relock if OS is upgraded?

hi nokia2003. when you say unlocking fees, can you advice me on where i can do this? is there a contact or something that you can provide me?

no, provided that you restore your unit immediately to complete the unlocking process, upon receiving the text message (asking you to do so)


however, there are reported cases that the iPhone was locked back to the carrier upon a new firmware upgrade. these reported cases are the minority and could be attributed to the above.

Added on May 3, 2009, 2:56 pmi'm not gonna elaborate the entire process in detail, but will give a gist of it.

first you need to determine the carrier that it is locked to (optus? vodafone? telstra?). if you are in doubt, you can try to ring the apple (australia) customer service and provide them with your IMEI number. or of course you can opt for the old fashion, conventional manner (like how i did for a friend), locate all three sim cards (doesn't matter if it's prepaid or not) and conduct a trial and error experiment.

once you have determined the carrier, then ring up that respective carrier for further information on how to unlock the iPhone (for optus, the general thumb rule is to have at least $120 of prepaid credit loaded inside). wait for the text to come in (suggested waiting period is 10 days, but typically it takes much less) and from what i have gathered in the OZ forum, the text might sometimes be a case of "lost in transition". hence you can always try to restore your iPhone via iTunes and then try with another foreign sim card.

actually i have an oz unit thats is locked with optus.
ive unlocked it by calling optus and providing them with my friends details in oz
10 days later i unlocked it by using my friends optus sim and connecting to itunes.

but the problem is now im afraid that if i update to the latest firmware it would get unlocked again
because i dont have that optus sim with me already.

any solutions ?

if you have restored your iPhone via iTunes after you have received the text, you ought to be alright (the restoration process essentially records your IMEI on their database and hence it is imperative for you to do so).

however, if the bad star decides to shine upon you, no worries as well, because you can always ring optus to complete the process again.




AFAIK, calling australian landline numbers, using the maxis IDD combination number will only cost you RM0.20/minute. you can even attempt to "boil porridge" or "bergayut telefon" with the consultant if you have the time to spare!

not to worry, ive been updating my FW for sometimes now using my optus iphone... and it is still unlock...
but still if problems occur..., u can always call optus back like nokia2003 said.... but it is really a minor case....

hi nokia2003...sorry to bother you..the thing is i bought the iphone from a guy in the forum.
what i've being told me is that the phone is from OZ phone
how do i check/double confirm which country is the phone from?

even so...if i find out the carrier..how do i buy the prepaid cause the reason being is that i dun have any OZ prepaid...

do you think there is any shops that can help?

need your help....

for starters, read Section B to determine the origin of the iPhone

my iphone 3g show "No Service" on screen...
im using turbo sim..
fw 2.2.1 (5H11)
02.30.03
my iphone from ireland..

make sure turbosim is meant for firmware 2.2.1 bb 2.30.03,
make sure 3g is off, swap simcard to some unlocked phone like nokia or w/e then search for network and select it, then swap it back to your iphone.
if still no network n ure using maxis, call them and tell them to disable ur 3g then try same method again. good luck.

ouh mann...how i want 2 surf the net w/o 3g...oiyooo...

turbosim is like that

so i cant surf inernet la if i use turbo sim?

Yea disable 3G. The problem is within the phone itself.

I got my phone from Rogers, a Canadian cellphone carrier. I did not jailbreak/unlock my phone (since I'm using the carrier, I do not need to unlock it). With the 3G on, I was able to receive call, but the line will be cut within few seconds. But the phone will work finely after a reboot. After several days, the problem is back. Then the Rogers guy told me to tuen off 3G and it works perfectly fine after that

Added on May 26, 2009, 9:50 pmHA I can answer question about turbo sim. I am a turbo sim user.
First of all, do not get panic when u see "No Sim" or "No Service", however you should be nervous when u see "Invalid sim".
Getting turbo sim to work is a lot of work and requires alot of patient. It took me 4 hours to get it to work.

Spycat, try resetting your network setting. more detail read http://forum.lowyat.net/topic/1008190/+71

About 3G, you can still surf net with EDGE or WIFI.

FYI, turbosim is not the best but is the only solution available to unlock v2.2.1 iphone. On the 3g when you want to surf, off it when done n putting the phone in standby. Get reputable turbosim, they are more stable compare to the copycat - u get what u pay for. I am oversea now n business will resume after june 2nd, sorry to all cause got no roaming services, pm will do for now.

my iphone is 3g 16gb, using gevey turbo sim...
anyone using iphone 3g 16gb face tis problemtoo?
i try the digi prepaid line ok..
then i try the postpaid one, always repeat said "no sim" then key the pin code, then repeat n repeat..
anyone knows what happpen?

Try disable the PIN?
