Docomo simcard regestration failed


Try other company sim-cards......if they work....then try other docomo sim...if this works ur sim is faulty........get a new sim.......if ur set reads other co sim and not docomo....its ur sets fault.......u will have to change FEM(N2700 in pic.) ic...(as it has inbuilt duplex er i.e. antina switch which can cause this fault)... this ic can be obtained from a dead Nk2700....

There is another way to confirm this without dismantling ur set........switch on ur set with sim....ignore sim reg fail message.....go to menu>settings>phone settings>network>change this to manual >ok......now ur phone should search for network.....if it does not then either ur sim has fault or sim section......if it starts searching then let it search......after some time network service provider list will appear....on the top it should be tata docomo......if its not there then FEM ic to be replaced.....if it appears select it......if now sim registeration fail appears ....for ur and other tata docomo sim...then get software of ur set reloaded......if only ur docomo sim fails...get sim replaced

My smart roaming sim lost its signal..i dont know why but still it has a remaining balance..what should i do??


You can powercycle your phone. Turn off phone,remove the sim card,memory card, and battery. Wait for at least 5 minutes then after 5minutes,you can put back the sim card,memory card at battery. Try to check if your roaming card will again work. If this doest work you need to contact smart telecommunications and ask them to deactivate then reactivate the roaming of your sim. Because if your sim wont work,there will be no access for you to retrieve the load of your sim.

I need unlocking lg u890


i had a lg u890 mobile phone that i got unlocked but it had the same proble where i swithched on my phone it used to ask for the usim code..my old phone was locked to the 3 nt/wrk i got it unlocked so i could use my 3 nt/wrk sim card or any network simcard but i used vodafone 3g sim card.the code i used with my vodafone 3g network simcard in phone when switched phone on & it asked for usim sim code i inserted code i got & it shut the phone down then on again then it wld work with vodafone no bother at all it even came up with vodafone uk etc.but i had to reconfigure the sms/text telephone number aswell as reconfigure the mms settings & numbers etc aswell as reconfigure wap settings from 3g network to vodaphones.but after i got it all unlocked & settings changed etc & inserted a different 3g network simcard ie vodaphone/orange/o2/3g sim/t-mobile/tesco sim/virgin sims & switched phone on it asked for usim code i tryed the code i have & inserted the same code i have it/they switched phone off & then back on & all network usim card worked with no problems at all.the code i have is.>>> 142358#*# thats 142358# * # all 1 item/action.once you insert that 142358#*# thats it your phone will shut down then restart up & go onto the network usim card you want to use or inserted before using code.but 1 thing tho please remember if u switch off your phone or your phone switches off as batterys run out no power u will need to insert the code again.& another thing code wont work if your phone switches off or you switch it off & plug your mobile battery charger into phone to charge your battery up on the phone & you switch you phone back on when you are charging your phone as the phone will switch on & say insert usim code if you enter the code the phone will switch off & back on again but it will still request usim code.so you will have to wait unto there is plenty of charge in the battery to take phone off charge & swithch your phone on get the usim code message insert code above phone will switch off & straight back on again & then it will go onto your prefured usim card then you can plug your charger into phone again to charge phone up.you can use your phone on charger when u have entered usim code & it switched off & on again & registered with the prefered network.i hope this is of use to you as it is to me.if you try this code & either if it works or not please can you let me knows ty.email watsonwhizzy2001@yahoo.com
