Does anyone know what process is necessary to get a cell phone to accept a 5-6 digit no. instead of it’s phone no. to send a text message and auto return text display? It seems like it is like entering in a text no. that is rewritten as http e-mail protocol and then the return message is the auto reply. any suggestions

I have only ever tried this with a small number of phones, but most phones store service load (SL) and service indication (SI) in the same place.
Differences are:
- With SI, the sender gets to pick a text associated with the link
- With SL the device shows the link itself
- With SI the sender can specify expiry or can send another WAP push to delete an unread SI message previously sent
- With SL the device can pop up some dialog, like ‘Open now’, ‘Later’ or ‘Discard’. Not all phones do this.
So SI gives the sender much more control, but SL is more ‘in your face’, but both messages end up in the WAP inbox.

You’re welcome. I just wished I had more time to write articles.

If you could post a link to my blog that would be much appreciated.

Thanks,

Franco,

All phones that have a browser will highlight a URL in a plain text message (except for maybe the first generation WAP phones, but these are phones from the last millennium).

This is not exactly a WAP push:
- a WAP push (Service Indication) typically is stored in its own Inbox, separate from the SMS messages (depending on you phone model)
- a WAP push lets you set a text like “My Web Site” that links to a URL, without the URL being shown
- this can also be achieved with an SMS PDU by adding a special Information Element in the UDH, though not many device support this
- and WAP push has the Service Load variant which would cause the URL to be loaded automatically (user experience varies a lot per phone model)

In all I’d say sending a URL in a plain text SMS message is probably the most reliable thing you can do.

Have sent links of the type http://www.xxxx.com
via simple sms (Text Mode) to my SonyEricsson w200
and the phone highlights the link and when you click on it it takes you to the site.
Can this be called Wap-Push.
The complete link has to be exposed; in your example the link is like hidden.
Do most of all phones support my way of sending a link?
Or should I use pdu mode to improve my coverage?
Will appreciate for your expert answer.

Franco
