Why won't Nokia 220 send texts

SOURCE: My Nokia N73 cant recieve text messages, it can send but cant receive.... :(

Hi.
I have had the same problem with my nokia N73. Please check your SMS center number if it corresponds with the network you using, and that it has the complete digits typed in. And also, try to communicate with your network oprator to get your SMS center number. Good luck

Hi,
This is a common problem. But there is a solution for this problem.
go to Messaging. Then hit Options. Scroll down to settings.
Hit text message. Options - Then "Message Centres".
Hit the Edit button and the following number should come up:

+47973100973
Save it and try sending messages. If again the same problem exist then call up your customer care who provides the services of your phone like Airtel, Reliance etc.. Ask the message center number and follow the above steps and save that service center number. Hopefully it should work. Thank you......

If the SIM works fine in other phones, there is a phone issue. See if you're eligible for a warranty replacement (eligible if purchased new from AT&T within the last year or if purchased refurbished from AT&T within the last 90 days). If ineligible and you have insurance, use it... there will be a $50 deductible applied to your next bill. If ineligible and you haven't got insurance, get a replacement through somewhere like ebay or craigslist, upgrade (never EVER use wirefly or amazon, trust me) through AT&T preferably, or purchase a gophone (AT&T prepaid) from walmart, walgreens, wherever (If you go to RadioShack, they'll do everything for you). You just put your SIM in it and it will have your phone number and contract information... you don't have to sign up for prepaid service.
