You cant. Because in this model of telephone you cant to changing plase of SMS storing to phone memory and thay storing in SimCard.
Elso if you use a high capacity SIM you can store more SMS. and there are special sim cards available named supper sim. you it has good capacity and you can copy you sim to supper sim by using sim card reader

you cannot increase sms capacity in w810i

i also believe that you cant increase the amount of SMS messages you can save
