My LG neon phone is having problems receiving long messages

I suspect it's related to your sim card (network), not your samsung cell phone. In most cases, regarding text messages, the problem is from the Service Operator. Have you tried the sim card on another phone? If not, remove the sim card, insert it on another phone and try sending a message from another mobile to you number, or you can do it in vise versa by inserting another sim card on your mobile.

If you can't receive text messages even it's inserted on another handset, then you need to call the customer care of your Network Operator and tell them your problem, they will help you fix it immediately.

You can check the message center number, but I don't think it's very much important in your case, well, if you wanna try, just check the text message settings and verify that the message center number (which is currently in use) is the same number which is on another phone with the same network (the other sim should be of the same network in your area). If it's different, make the changes and save the settings. Also disable the "Receive Via" or similar settings.. (I can't recollect the exact settings as i don't have the same model with me, please excuse me for this.).

If the same sim card doesn't receive text messages using another handset, don't bother to change the settings or to make any changes with it, first call the customer care and verify from them, you may make mistakes instead of fixing it.

I had the same problem, so i went down to ATT and told them about it and they got on my phone and put everything back to how it was!! I couldn't recieve mms messages and some music files!! You might have changed some kind of setting that you don't remember and thats why it's happening!! Thats what i did!! just take it in, they will fix it for free in like 5 minutes!!

reset u phone or check u text setting.

hi there,
call the customer service of your service provider ( AT&T,Vodafone,Verizon etc)....they will set up message center number on your phone , the one that you have might be incorrect...your mobile operator will send you sim updates that will refresh the settings ....and then you will get the text message options
cheers

okay this hapened to me what you do is go to you message menu go to message settings and go to text message then you have to go to message center number make sure the number matches the one given to you in your user manual

i dont think u can

you have to wait till the end of messages then it lets u add contacts

take it into the store and see what is wrong with it because i have the same phone and it doesnt have any problems

i hate my lg neon sooo much    its been 2 months and it doesnt work and it fell apart and i havnt told anyone    i had to snap it to gether but it is so fragille and wobballly

it means your inbox is full.. in most cases anyway or that your phone is stuck on the text message icon.. it will go away afterawhile i had the same problem with my lg
