-\r
-<p>You can send from your phone short text letters. And this is SMS\r
-(Short Messaging System).\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">What is SMSC ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>This is Short Messaging System Centre.\r
-\r
-<p>Idea is simple: when you write\r
-your SMS, select recipient(s) and send your SMS, it's send to SMSC.\r
-If you see "Message sent" ot something like that, don't worry. It means,\r
-that your SMS was delivered to SMSC and SMSC try to delivery it to recipient(s).\r
-\r
-<p>Why is it done this way ? Let's say, that recipient's phone is disabled.\r
-If it will done this way, that your phone will try to delivery it directly,\r
-it will loose energy during each try and you have to be in network coverage\r
-during it. GSM network makes it easier - not you, but SMSC try to delivery it.\r
-And of course, you can decide, how long it should be done (after it SMS will\r
-deleted).\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">What SMSC should I use ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>The most simple answer is: ask your operator and use its' own SMSC.\r
-\r
-<p>But sometimes it's not so simple: it's possible, that SMSC of your operator\r
-CAN'T send SMS to some other network. You should try to use different SMSC then.\r
-But remember: if you will try to use SMSC from different country, you have\r
-to have activated international calls.\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">Can I use my own SMSC in roaming ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>Yes.\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">Can SMS contains not only text ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>Of course. Each SMS contains some bytes filled with contest. Normally they're\r
-filled with chars. But of course you can decide, that they have different meaning\r
-and send +binary data this way too...\r
-\r
-<p>In this moment we can classify SMS to:\r
-\r
-<p>\r
-<ul>\r
-<li>7 bit SMS - you can put each of 127 chars into it</li>\r
-<li>Unicode SMS - you can each of 65550 chars into it</li>\r
-<li>binary data SMS - ringtone, picture, etc.</li>\r
-</ul>\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">What is length of SMS ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>Each SMS can contains ONLY 140 8 bit chars. When you code it as 7 bit SMS,\r
-you can save 160 chars (you have 140*8 bits inside and they're divided into\r
-7 bits) and when code as Unicode SMS, 70 chars (each char in such SMS contains\r
-of 2 8 bit chars).\r
-\r
-<p>It's also possible to put into each sent SMS\r
-special flag, which will mean: this\r
-is first, second, third,... part of SMS. Some phones can display this info\r
-(for example info "Linked: 1/...") or even display each SMS with such flag\r
-as one long... Such SMS are called concatenated or linked.\r
-\r

-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>Ask your operator :-)\r
-\r
-<p>Generally you pay for EACH SMS with 140 8 bit chars. It means, that\r
-after sending Linked SMS consist of 2 such SMS, you will pay for 2. The similiar\r
-thing is with Picture Images (each of them consist of 3 SMS) and Reminders\r
-from Nokia 3310 (2 SMS).\r
-\r
-<p>Something it's free. When ? When you are in roaming and network, you use,\r
-write in logs, that sent SMS, when it was send ONLY over SMSC of this network (remember:\r
-you can you SMSC from your home network). Or when SMSC, you used, gives info\r
-to network about error during sending, but send it correctly !\r

-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>In many networks it's free...\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">What is SMS class ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>Each SMS have flag with info, what should be done with it after delivering\r
-to recipients' phone. There are 4 possiblities (classes):\r
-\r
-<UL>\r
- <LI>Class 0: displayed immedietaly after receiving\r
- in display of SMS recipient</li>\r
- <LI>Class 1:</li>\r
- <LI>Class 2: saved in SIM card of recipient</li>\r
- <LI>Class 3:</LI>\r
-</UL>\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">What is delivery time ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>This is the time, during it SMSC will try to delivery your SMS.\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">What is delivery raport ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>You can know, if your SMS was delivered to recipients' phone\r
-(don't misguide it with reading !). It's free. There are two ways\r
-to do it:\r
-\r
-<p>\r
-<ol>\r
-<li>enable such option in your phone. Of course, it will work\r
-only, when used SMSC will accept this feature</li>\r
-<li>write special text on the start of SMS. It can be different for\r
-each SMSC</li>\r
-</ol>\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">What it "Reply via own centre" ?</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>Theoretically, when you send SMS with flag to somebody, it should\r
-be able to send answer over your SMSC. Often it doesn't work (many SMSC\r
-doesn't accept SMS from forbidden networks even with this flag).\r
-\r
-<p><font color="#1F409F" size=+2 class="dzial">I have error, when answer to received SMS</font><br>\r
-<hr align="LEFT" size="3" width="300" color="#60c0a0" noshade>\r
-\r
-<p>\r
-<ul>\r
-<li>you don't have correct SMSC in phone</li>\r
-<li>person, who sent SMS to you, marked "Reply via own center" option.\r
-Try to send SMS over your own SMSC</li>\r
-<li>you can't send SMS (don't have it activated in your operator)</li>\r
-</ul>\r
