Most of the time I can't get connection to internet. and I get message that there is no connection. I feel, I'm paying montly payment for nothing. The Samsung S2 that I have also get frozen very often. I'm frustrated and am thinking to change my phone to other company.
What should I do?
Hey there Bruce!
how long have you had the phone for ? have you tried a factory reset? if not this usually helps the problem with most phones. Contacts should be saved to your Gmail account if not you can go into contacts tap the menu button merge accounts and merge with Google. you can also save to the SIM card and well selecting import/export and export to SIM :)
if you have pictures and an SD card the pictures will be saved to the SD card. If you have Google photos on the phone you can back them up through Google photos and the moment you sign back in with your Gmail account the pictures and contacts will show up :)
By internet, do you mean using data or wifi? Changing your phone to another company won't fix those issues unless it is data that your phone can't connect too (that could be a coverage issue).
The s2 is a very old device now, so for it too lag is not uncommon. I remember a friend of mine used to have an s2 which had trouble connecting to wifi but i could connect just fine. I think the reason was that the s2 had older gen wifi built in. A new phone will probably be the best solution to your issue. I suggest a moto g or an N5
