Tip & How-To about Cell Phones

How to boost cell signal when service is poor

If your cell signal is going down especially in an area you normally have good service in or if you never turn your phone off with cdma technology( verizon, alltel, tracfone, ...no sim card) if you dial *228 from your cell hit send like making a cal and press option 2 it will update the phones signal and roaming capability and any new updates that your phone may not received due to bad area travel or not powering the phone on and off. It usally increases by one to two bars and if you are unable to get it to go through drive into town near any verizon wireless store they all have cell towers near them and try again. this can be done any time any where there is cell service within the continental u.s. and I do it if I travel from my home to the town 30 miles away because the signal changes so dramatically between towns. just a tip if your bars are dwindling away to nowhere.

i have a samsung through cricket and i live in colorado i took a plane to georgia and when i got there my phone didnt work and it said CDMA service not available how to i fix this


Hi,

This only means that there is no CDMA coverage on that area where you're at. For sure you'll have it back where CDMA signal is available.

If you go to http://answers.yahoo.com/question/index?qid=20071231123152AAcz6sl you'll see that it is for the same reason

it means that there is no native or partner'd CDMA service
your phone may be able to pick up GSM frequencies but b/c Verizon is CMDA your phone can't not use GSM service
Source(s): Verizon network is CMDA
Sprint use CDMA, iDEN and a few others
the only national carriers that use GSM are T-mobile a German companies and ATT a US monopoly company
no major in the USA uses analog signals

samsung B209 network Problem does not show the network and dose not connect the call


Welcome to FixYa!

It means that there is no network coverage in your area. In most cases, your operator or service provider is the best source of assistance with issues regarding network coverage.

When you are in outdoors, move your position to find a good signal network coverage area. When you are in indoors ( like building, basement and subway station), change your position by small spaces, or move towards a window.

If other mobile phones with the same operator or service provider as yours does not have a signaltoo, then it is conclusive that there is no network coverage.

If other mobile phones with the same operator or service provider as yours does have a signal, then you need to upgrade your cell phones firmware. Unfortunately, there is no upgrade available from Samsung's Website http://www.samsung.com/in/consumer/mobile-phone/mobile-phone/cdma-phone/SCH-B209ZKAREL/index.idx?pagetype=prd_detail&tab=support


Samsung B209 uses CDMA Technology at 800Mhz frequency. If your operator or provider uses GSM Technology, then your phone will not get any signal.

Thank you for using FixYa.

Have a great day.

icon


EV-DO this is a normal icon especially on e815 Verizon phones.
EV and EV-DO stands for Evolution Data only. Evolution data Optimized. Like CDMA Technology but faster and better for certain features. So don't worry about it, is just part of the E815.
Thank you
